[Bug c++/40048] New: Compiler crash possibly related to --std=c++0x

[bgalehouse at spamcop dot net]

The following was produced on a gentoo x86 linux system with a pentium-m
processor, the system compiler is Gentoo 4.3.3-r2 and kernel is
linux-2.6.28-gentoo-r5. 

Last night, I built gcc 4.4.0 and installed it into /home/bgalehouse/installs. 
I then reconfigured a library (CGAL) to make use of c++0x features, and tried
to compile a program. This program worked fine under the system compiler when
the library is configured to avoid c++0x features. I might have time to compile
and try a recent snapshot over the next few days, if so I'll try to amend this
bug report accordingly.

[Bug c++/40048] Compiler crash

------- Comment #2 from bgalehouse at spamcop dot net  2009-05-06 16:04 -------
Just found that it seems unrelated to c++0x features. I configured the library
to not require them, and found the 4.4.0 crashes but the system compiler works.
(both running same options, without the -std=c++0x, but otherwise as
previously)

I'm happy to provide additional .ii files and so on if necessary.

Works for me on the branch head.
