Guys, we already know the problem.  We are hitting an annoying x87 FPU
design 
flaw.  You can read all about it here if you are interested:

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=323

And there is a good paper on it here:

http://hal.archives-ouvertes.fr/docs/00/28/14/29/PDF/floating-point-article.pdf

We don't need any more compile reports.  If you are on an architecture
that uses 
the x87 FPU and you haven't forced SSE or float-store then you will see
this 
problem.

cluttering the bug report.
