You may find this article helpful. It is focused on memory leak detection on embedded systems but it should apply equally well to regular Linux systems.

there is a tool called mtrace

modify source code to
#include <mcheck.h>

then invoke mtrace();
at the beginning of main.

export MALLOC_TRACE=memory.log
and run the programm

then
mtrace my_program $MALLOC_TRACE


also you can use the ccmalloc library as a replacement for malloc and free
as a way to trace mem allocation

also a tool called "Electric Fence"
you can link against that will stop at any bad read/write and tell you what happened
this is the only way i know of to find illegal reads so it's kind of important.
this one will do lots of different stuff by setting SHELL variables so read the manual.
