I don't think this is out of memory, I think this is a real compiler
bug.  The crash is in the same place for both failed builds:

database_check.cc: In function 'void report_certs(const
std::map<revision<hexenc<id> >, checked_revision,
std::less<revision<hexenc<id> > >, std::allocator<std::pair<const
revision<hexenc<id> >, checked_revision> > >&, size_t&, size_t&,
size_t&, size_t&)':
database_check.cc:835: internal compiler error: Segmentation fault

The function in question is not terribly complicated - and compilation
of several more complicated functions/files has already succeeded at
the point where the buildd failed.
