I get the 'Assertion failed' message in malloc:

malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *)
&((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd))))
&& old_size == 0) || ((unsigned long) (old_size) >= (unsigned
long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 *
(sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size &
0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.

Talk to your distribution maker.  You are not using a standard glibc and
haven't verified it happens with the current code.  You haven't provided any
way to reproduce it.  You can reopen the bug if you have a reproducer which
displays the problem with the current upstream.
