It looks like memory corruption in your program; try setting MALLOC_CHECK_ environment variable to 1, 2, or 3, before running your program. MALLOC_CHECK_ with those arguments will ask the standard malloc(3) to perform more checks on the heap corruption. (Maybe 2 or 3 would be more useful, since they abort(3) the program immediately.)

If the simple MALLOC_CHECK_ doesn't track it down for you, you may need to use Valgrind to find your error. (Another option is to try a debugging memory allocator, but I've never used one.)
