Thanks.  I think I see the problem, and I'm testing a solution.

However, I'm surprised that you see this on a 64-bit host.  Could you
please run an unoptimized build under GDB, put a breakpoint in
memory_full, and see if that breakpoint breaks?  If it does, please
show the backtrace from there.  I'd like to make sure the problem I
see is the same one that affects you.

Also, how much virtual memory (RAM and swap) does your system have at
its disposal?
