[Bug middle-end/34450] New: [4.3 Regression] compile takes up 1.8 GB RAM at -O1

[tbm at cyrius dot com]

Compile the attached source with -O1 and it will take roughly 1.8 GB RAM
on x86_64 and over a minute with current trunk.  4.2 took a few seconds
and less than 200 MB RAM.  Granted, this is with checking on because
I haven't had a chance to compile a version without checking, but this
still looks like a regression.  Hopefully someone (Richi?) can take a look.
