Something OP called, which corrupted heap.

There are a couple of packages that can assist you in discovering who
this is, e.g. electric fence.

Valgrind is almost certainly a better suggestion than efence.

It certainly is a good tool, but it depends upon the size and runtime of the program.

EFence allows your program to run at almost normal speed (at the expense of a huge virtual address space) while "programs run significantly more slowly under Valgrind" (http://www.valgrind.org/info/about.html) as valgrind interprets your program.

It's a kind of space vs time tradeoff.
