I think I'll downgrade gcc(until further notice).

Please split this PR into two separate reports.

Also, please attach standalone preprocessed source that triggers the bug, see
http://gcc.gnu.org/bugs.html.

A backtrace of the crash would also help a lot.

Alright,
(I'll have to read read up on the backtrace part),
from what I'm seeing so far, not good, i.g. evolution
compiled perfectly(with the latest snapshot of gcc),
but as I'm running the mail client 
I'm getting skips in the music(streaming from the intranet),
when I minimize and maximize the window.

for some reason I'm thinking it might have something to
do with libpthread(not sure though, maybe the headers
got messed up)
Anyways I'll try and supply as much info as possible.

regards,

Justin P. Mattock

Please attach preprocessed source and the output of -v appended to the
commandline.

The backtrace is important for targets that are not so widely used (so
developers sometimes won't have to build a crosscompiler to confirm the bug).
On i386, it will earn you extra bonus points ;) It is the preprocessed source
(standalone, and reduced as much as possible) that matters.

Please report on which target and which gcc revision you have this problem.

operating system= LFS(used ubuntu for the starting of the creation,
then moved the new system over as soon as ready)

arch(tough to say) when compiling every lib/app I used  CCFLAGS(example)
CFLAGS="-march=core2 -mtune=core2 -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"
MAKEOPTS="{-j3}"

I'm guessing it's setting the system at x86_32(but could be setting it at
x86_64)

As for gcc: the latest snapshot(I'll have to give you the number later, seems I
can't connect to the
snapshot server to supply the release number).
