As Angelo said, the answer to both questions is "No". But there's actually a big difference. First, the 'abort' breakpoint is never hit. Second, there are no more SEGVs reported in glib. There are lots of SEGVs in _malloc_internal_nolock, and some further SEGVs that gdb can't pinpoint. I think all of the crashes in _malloc_internal_nolock are coming when it's called by special_realloc. Maybe the latter needs to be calling _malloc_internal instead of _malloc_inernal_nolock. I don't have any more time right now, but I'll try that later.
