Preprocessed source that triggers the ICE

I hope there's some way to reproduce this on a platform different then alpha :)

it'll take me some time to reproduce this

the .ii works fine on amd64/x86

Some more details:

with -O2, it gives no error at all

This seems to work with 4.1.2.  Could someone else please verify that though?

Thanks

Tested with gcc-4.2.2, seems to work now.
