First entry so please stay calm and point me towards to your rules to apply to
them.
I tried to use GCC4 to compile a whole LFS toolchain. I compiled several
GCC-4.X.X with GCC 3.4.3 and furthermore started to compile using GCC4. I used
pretty clean environments based on LFS.
No matter what I did here is the last command which seems to cause the failure:

I hope I sent not to much or less information. This is completely reproducable.
Using gcc-3.4.3 in exactly the same environment does work properly.
Contact me , when you need further information. I have the .i and the .s file
when somebody needs them.
Thanks Tobias
