    My guess is that it crashes just due to vm exhaustion (i.e. NULL
from malloc returned somewhere and passed there). I also can imagine I
know the reason why so much core is used at all - due to the way
virtual inline functions are handled by ld (remember, auto-import
problem was also related to this). The virtual inlines are spewed into
comdat (aka linkonce) sections, duplicated multiple times in object
files/ It seems that ld sifts them into non-optimal way: first, loads
them all together and only them starts hard shuffling to get rid of
duplicates, instead of doing the check on load. I faced the problem,
of course, but my solution was to split big dll into bunch of small
ones. I understand that's not the solution in your case, but it worked
for me, so I never really tried to test validity of the hypothesis or
fix it.
