Mainline space problem

[Bradley Lucier]

Right now, the bug in

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16852

is making it more difficult for me to test the correctness of the 
generated code.  (I know the code's not correct, but I'm trying to find 
a suitable test case to diagnose, and that's hard when some of the 
modules don't even compile because cc1 requires more than 2GB of RAM.)

It would be nice if someone could try to fix the problem here.  I don't 
know why it's still marked as UNCONFIRMED when Andrew has noted the 
precise allocation that fails.
