malloc-allocation-tracker

A custom malloc wrapper that keeps track of allocations in an allocation list

Why?

I was testing an application for memory leaks, and sadly I was not able to hook it to valgrind or the leak sanitizer So I made my own The idea behind it was that any program that uses malloc, can just be recompiles along with this static library, without the need to include or define anything

Requirements

• gcc
• make
• ar

Building

• Run make
• If all works out, the static library libmallocwrap.a will be created

Using

• You will have to include alloc_list.h in order to be able to access to allocation list
• Compile your program with cc yourcode.c libmallocwrap.a -ldl Make sure to link -ldl
• See the test directory for a working example

Issues

• The list functions are not thread safe
• The list delete function is very slow since it has to iterate through the list
• Instead of the regular libc malloc, mmap is used in the list functions
