https://bugzilla.novell.com/show_bug.cgi?id=671262

and its various duplicates report GCC crashes because of this
when using in a virtualized 64bit environment.  The KVM folks not
willing to fix things is is not direct information but from
conversation in that bug.

Googling also leads me to

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=671866

so we're not the only ones seeing this.
