[Bug c++/39869] New: Firefox 3.0.9 compilation with gcc 4.4.0 (segfault)

[fragabr at gmail dot com]

I have a Athlon64 X2 (Linux 2.6.30-rc3) and I can compile Firefox 3.0.9 fine
with gcc 4.3.3, but if I use gcc 4.4.0 it segfaults. My default optimization is
-O3. If I reduce to -O2, Firefox starts, but with huge letters and windows...

So gcc 4.4.0 is generating bad code trying to compile Firefox 3.0.9, because
gcc 4.3.3 compiles it just fine.

I thought it was best to report it here because it seens to be a regression in
gcc 4.4.0. Thanks.

What information do you need? Couldn't you compile Firefox yourself to test it?
Or if someone uses x86_64 I'm sure he/she will notice this.

Anyway just ask what you want. If I can provide, I'll reply as soon as
possible. Thanks.

Likely related to https://bugzilla.redhat.com/show_bug.cgi?id=487844
which is a nspr bug.
