It's not terribly helpful. It shows the obvious
signature of heap corruption, a crash in _int_malloc.
The bad code could be anywhere; your stack trace
does not point to the bad code. It is misleading.

To catch an overflow when it happens, right as
it is corrupting the heap data structures, you need
either valgrind or electric fence. Valgrind works all
by itself. Electric fence needs to be used with gdb.
