Mplayer always crashes quitting .flv video (either by pressing 'q' or
because the video is over).
The error is:
Assertion failed: (diff == regind * size), function
arena_run_reg_dalloc, file /usr/src/lib/libc/stdlib/malloc.c, line 1714.
Removing the assert at line 1714 and recompiling libc solves the
problem, but I'm not that familiar with the current malloc
implementation to know whether (diff == regind * size) is always
supposed to be true (thus a bug in mplayer) or the assertion is simply
wrong.
This is probably due to attempted deallocation of an invalid pointer.
This could be either a double free or a totally bogus deallocation,
perhaps of a pointer that is within a valid object.
Removing the assertion in malloc.c simply allows undefined behavior
beyond where the assertion failure would have caused a crash. The
failure modes can be serious, such as memory corruption or a
segmentation fault.
