Almost certainly a dup of 50326.

It looks like PR50326 is fixed so this should be fixed too if it really
a duplicate.  Matthias, do you still see this problem?

I'll check, however I don't see the fix for 50326 applied to the 4.6 branch.

Created attachment 25538
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25538
gcc46-pr50350.patch

I couldn't reproduce it with a x86_64-linux -> ia64-linux cross, that said, the
patch was easy to backport.
Could you please quickly verify if it fixes it?
So far I've bootstrapped/regtested it on x86_64-linux and i686-linux.

I'd like to roll gcc-4.6.2-rc1 later today or tomorrow, so the sooner you could
verify it the better.
