I investigated and couldn't find anything conclusive, so I said "seems" because
I wasn't certain.

If you assume I didn't investigate and reply with "time to adopt ICC" then feel
free to do so, I don't volunteer my time to GCC for people with that attitude.

I'm not interested, the point is you provided an incomplete bug report but are
then happy to complain about the effort put in by people who look at it.

The bug was fixed by http://gcc.gnu.org/ml/gcc-cvs/2009-04/msg00115.html so is
fixed in 4.5.0 and later
