To Steven:
I am assuming you are asking about the building of GCC - I did it through the
ports system of FreeBSD, using the latest update of the gcc45 port.
Additionally, I just did an update in my Arch Linux, which

To Richard:
Under my Arch Linux, the linker cmd (that triggers the bug) is:
bash$ g++ -O3 -g -Wall -Wextra -fomit-frame-pointer -ffast-math
-funsafe-math-optimizations -mtune=native -flto -msse -mrecip -mfpmath=sse

Well, I added nostdlib and removed all libraries from the cmd line, but
still:
bash$ g++ -r -nostdlib -O3 -g -Wall -Wextra -fomit-frame-pointer -ffast-math
-funsafe-math-optimizations -mtune=native -flto -msse -mrecip

From my two tests in FreeBSD and Arch Linux, it appears that the -flto bug
that is triggered on my renderer, has occured with the 20100520 (prerelease)
commits.
I hope this helps
Is there anything else I can

I am at work, so I did a fresh compilation of GCC4.5 from the 20050520
snapshot under my Debian stable using:
../configure --prefix=/opt/gcc45 --enable-languages=c,c++ --enable-lto
The bug still happens, even if I

I meant 20100520, obviously, not 20050520 (no flto back then! :-)
Anyway, if I understood correctly, I should wait for the next snapshot... ETA?

And now that we see that it happens even with one object file,
here is the preprocessed (.ii) for the code behind this object file:

I see. I was not aware of "mergeable", TBH - thanks for pointing it out (it led
me to reading about "data environments").
Thanks, Jakub.
