Cannot say something definitely with incomplete source code.
The bug is not necessarily in the malloc/free pair of this construct. Likely
you destroyed the heap structure in earlier memory allocation/deallocation
operations (e.g. during list processing). You may want to check your program
with a memory debugger, e.g. valgrind for i386 platform.
