Memory Allocation Tracker

Small API that keeps track of the of the allocated memory in the system

How it works

Include debug_memory.h (tested in Window 10 x64 using Visual C++ Build Tools 2015 and Linux using GCC)
debug_malloc(size_t) allocate memory, overrides malloc in debug
debug_free(void *) free memory, overrides free in debug
debug_print() print the allocated memory to stdout

Each memory allocation generats a node in a linked list with file name, file line, size of the allocation and call stack. When memory is free the node coresponding to the allocation is searched and remove from the list. To achieve thread safety a spin lock is used making each thread accessing sequentially.
