Ok, that's quite likely.

A regression hunt on powerpc-linux showed that the test starts passing with:

http://gcc.gnu.org/viewcvs?view=revrev=131823
r131823 | rguenth | 2008-01-25 12:06:31 + (Fri, 25 Jan 2008)

That's a fix for 33887.

This works for me using latest mainline, but using a compiler built with
revision 131553, it fails.  I'll try and see if we're just getting lucky now or
whether it has been fixed since then.

Janis, in the meantime, can you run a reg hunt on the attached testcase
starting at revision 131553?

Still works for me on x86_64/i686.  Any ppc guys around to confirm this?

This works for me on a x86_64 target.

(In reply to comment #2)
 This works for me on a x86_64 target.
 

For me it works on i686-pc-linux (with cross-compiler, configured with the same
method as above - crosstool-0.43 + glibc-2.3.2), works on i386-mingw32 (with
cross-compiler linux-mingw32), but does not work on powerpc.
