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.
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…
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++: 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++: 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…
C/C++: Bus error (core dumped) — SIGBUS from misaligned access or a bad memory-mapped file
The CPU or OS rejected a memory access that is not a plain invalid address: misaligned data, or touching a memory-mapped file pag…
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/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.
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…
Two steps away (22)
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.
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++: ==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.
C++: error: call of overloaded 'f(int)' is ambiguous
Two or more overloads fit equally well, so the compiler refuses to guess which function you meant.
C++: error: cannot declare variable 'x' to be of abstract type 'Shape' (pure virtual functions)
You tried to create an object of a class that still has pure virtual functions; only a derived class that overrides all of them c…
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++.
Segmentation fault (core dumped)
A program accessed memory it wasn’t allowed to, and the kernel killed it with SIGSEGV (exit code 139).
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…
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/C++: runtime error: signed integer overflow / null pointer / shift exponent too large (UndefinedBehaviorSanitizer)
UBSan detected code that triggers undefined behaviour (overflow, null dereference, out-of-bounds index, bad shift, misaligned acc…
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).
fork: Cannot allocate memory / ENOMEM
The kernel refused a memory allocation — RAM and swap are exhausted, or overcommit/cgroup limits block it.
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…
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.
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::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…
MSVC: error C2065: 'x': undeclared identifier
Visual C++ met a name it has not seen declared — a typo, a missing header or namespace, or use outside its scope.
C/C++: warning: comparison of integer expressions of different signedness: 'int' and 'size_t' [-Wsign-compare]
A signed integer is compared with an unsigned one; the signed value is converted to unsigned, so a negative number becomes huge.
MSVC: fatal error LNK1104: cannot open file 'foo.lib' (or 'app.exe' while it is running)
The Visual C++ linker could not open an input library or the output file — the path is wrong, the library is missing, or the .exe…
