Argh that's right.  We do compile this correct with -O1 or higher, it
seems to fail only with -O0.

Dylan, can you please fill in a complete bugreport using the gccbug
script or the web interface on gcc.gnu.org?  Please follow the
instructions at http://gcc.gnu.org/bugs.html, especially provide
preprocessed sources and try to generate an example that's as small as
possible.

Thanks,
Andreas
