Looks like malloc is throwing. Maybe out of memory error?

malloc() doesn't throw, period. It's an inherited C function, and
returns NULL on failure to allocate. If it's crashing during a malloc()
call, then the likely reason is that the free store was corrupted,
often from overrunning a dynamic array.

Without the code, it's hard to say.

HI,
What's the possbile reason for the following core?
They were from the same process, but the cord place was not the same
each time there was core dump.

I would wager that you have deallocated something twice.

malloc () crashes suggest the heap is corrupted. The best way to to
that is to dealloc things multiple times.
