Fix assertion in malloc.c:tcache_get.
One of the warnings that appears with -Wextra is "ordered comparison of pointer with integer zero" in malloc.c:tcache_get, for the assertion: assert (tcache->entries[tc_idx] > 0); Indeed, a "> 0" comparison does not make sense for tcache->entries[tc_idx], which is a pointer. My guess is that tcache->counts[tc_idx] is what's intended here, and this patch changes the assertion accordingly. Tested for x86_64. * malloc/malloc.c (tcache_get): Compare tcache->counts[tc_idx] with 0, not tcache->entries[tc_idx].
