C/C++: ==ERROR: AddressSanitizer: heap-use-after-free on address — memory used after delete/free
The program read or wrote a heap block after it had been freed; ASan shows who freed it and where it was allocated.
Segmentation fault (core dumped)
A program accessed memory it wasn’t allowed to, and the kernel killed it with SIGSEGV (exit code 139).
C/C++: ==ERROR: AddressSanitizer: heap-buffer-overflow on address — READ/WRITE of size N
AddressSanitizer caught a read or write just outside a heap block — an array index or length that is off by one or more.
C++: terminate called after throwing an instance of 'std::bad_alloc' — what(): std::bad_alloc
`new` or a container could not get the memory requested — either the system is out of memory or the size was absurdly large (ofte…
C/C++: free(): double free detected / double free or corruption (out) — Aborted (core dumped)
Memory was freed twice or the heap was corrupted (buffer overflow, freeing a non-heap pointer), so glibc aborted the program.
The application was unable to start correctly (0xc0000005) / Exception code 0xc0000005 access violation
A program tried to read or write memory it doesn’t own and Windows stopped it — buggy software, bad drivers/plugins, security sof…
fork: Cannot allocate memory / ENOMEM
The kernel refused a memory allocation — RAM and swap are exhausted, or overcommit/cgroup limits block it.
C/C++: *** stack smashing detected ***: terminated — buffer overflow on the stack
GCC's stack protector noticed that a local buffer overflowed and overwrote the function's canary value, so it aborted the program.
Killed / Out of memory: Killed process (Linux OOM killer)
The kernel ran out of memory and killed a process to recover — the program just prints “Killed” (exit code 137).
Blue Screen: MEMORY_MANAGEMENT (Stop code 0x0000001A)
Windows detected a severe memory-management error — commonly faulty RAM, unstable memory settings or a bad driver.
C/C++: Segmentation fault (core dumped) — SIGSEGV from a null, dangling or out-of-bounds pointer
The program touched memory it is not allowed to access — a null or dangling pointer, an out-of-range array index, or a stack over…
C/C++: stack overflow — infinite recursion or huge local array (Segmentation fault, 0xC00000FD)
The call stack ran out of space, typically from recursion that never stops or from a very large array declared as a local variabl…
Two steps away (31)
C++: error: no matching function for call to 'f(int, const char*)'
No overload of the function accepts the arguments you passed — wrong count, wrong types, or a missing conversion.
C++: error: 'int X::secret' is private within this context
Code outside the class tried to use a private (or protected) member.
Linux: version `GLIBCXX_3.4.30' not found (required by ./app) — libstdc++.so.6
The program was built with a newer GCC than the libstdc++ installed on the machine where it runs.
Kubernetes: CrashLoopBackOff
The container starts, crashes (or exits), and Kubernetes keeps restarting it with increasing back-off delays.
RangeError: Maximum call stack size exceeded
A function called itself (directly or indirectly) too many times — usually infinite recursion.
RangeError: Invalid string length
A string grew beyond the engine’s maximum length — usually runaway concatenation or huge JSON.stringify output.
C/C++: Assertion `x > 0' failed. Aborted (core dumped) — assert() condition was false
An `assert()` in your code or in a library found its condition false and aborted the program on purpose.
C++: terminate called without an active exception — std::thread destroyed while joinable
A `std::thread` object was destroyed (or reassigned) while its thread was still running, so the C++ runtime called `std::terminat…
C++: pure virtual method called — terminate called without an active exception
A pure virtual function was called on an object that is being constructed or destroyed, where the derived part no longer exists.
C++: terminate called after throwing an instance of 'std::out_of_range' — what(): vector::_M_range_check
A C++ exception wasn’t caught anywhere, so std::terminate aborted the program. what() tells you the reason.
C/C++: ==ERROR: LeakSanitizer: detected memory leaks — Direct leak of N byte(s)
At exit, LeakSanitizer found heap blocks that were allocated but never freed and are no longer reachable.
Kubernetes: OOMKilled (exit code 137)
The container used more memory than its limit, and the kernel killed it.
java.lang.OutOfMemoryError: Java heap space
The JVM ran out of heap memory and garbage collection couldn’t free enough.
Fatal error: Unexpectedly found nil while unwrapping an Optional value
Swift force-unwrapped (`!`) an optional that was nil, crashing the app.
The application was unable to start correctly (0xc000007b)
A program loaded a DLL of the wrong architecture (32-bit vs 64-bit) or a corrupted runtime library.
FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory
The V8 heap hit its limit — a large build (webpack, tsc, Next.js) needs more memory, or the app leaks.
MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 listeners added
More than 10 listeners were added to one event — often a leak where listeners are added repeatedly.
Error: listen EADDRINUSE: address already in use :::3000
Another process is already listening on that port.
Error: write EPIPE
Node wrote to a pipe or socket whose other end was already closed.
RangeError [ERR_CHILD_PROCESS_STDIO_MAXBUFFER]: stdout maxBuffer length exceeded
child_process.exec/execSync produced more output than its buffer allows (default 1 MB).
C: warning: format '%d' expects argument of type 'int', but argument 2 has type 'long int' [-Wformat=]
The `printf`/`scanf` format specifier does not match the argument's type, which is undefined behaviour and prints garbage or cras…
C/C++: Floating point exception (core dumped) — SIGFPE, usually integer division by zero
Despite the name, this is almost always an integer division or modulo by zero (or INT_MIN / -1); floating-point division by zero…
MSVC: error C4996: 'strcpy': This function or variable may be unsafe. Consider using strcpy_s instead
Visual C++ treats classic C library functions such as `strcpy`, `sprintf`, `fopen` and `scanf` as deprecated or unsafe and, with…
PHP Fatal error: Allowed memory size of X bytes exhausted
The script tried to use more memory than PHP’s `memory_limit` allows.
Composer: PHP Fatal error: Allowed memory size of 1610612736 bytes exhausted
Composer ran out of memory while resolving or installing dependencies.
FATAL: the database system is in recovery mode
PostgreSQL crashed (often OOM-killed) and is replaying WAL to recover.
Blue Screen: IRQL_NOT_LESS_OR_EQUAL (Stop code 0x0000000A)
A driver accessed memory at an interrupt level where that’s not allowed — almost always a faulty or incompatible driver, sometime…
Blue Screen: CRITICAL_PROCESS_DIED (Stop code 0x000000EF)
A process Windows can’t run without (csrss, wininit, smss…) stopped unexpectedly, so the system halted.
Lambda: Runtime exited with error: signal: killed (Runtime.ExitError)
The function process was killed — almost always because it ran out of its configured memory.
C/C++: warning: control reaches end of non-void function [-Wreturn-type]
A function that promises a return value can finish without returning one on some path — undefined behaviour in C++.
C: warning: implicit declaration of function 'foo' [-Wimplicit-function-declaration]
In C you called a function the compiler has not seen declared — usually a missing `#include`. Newer compilers treat it as an erro…
