I don't understand what you're saying.

On my linux box

heine:~/Downloads> uname -a
Linux heine 3.0.0-13-generic #22-Ubuntu SMP Wed Nov 2 13:27:26 UTC 2011 x86_64
x86_64 x86_64 GNU/Linux

and with this compiler:

heine:~/Downloads> /pkgs/gcc-4.6.2/bin/gcc -v
Using built-in specs.
COLLECT_GCC=/pkgs/gcc-4.6.2/bin/gcc
COLLECT_LTO_WRAPPER=/pkgs/gcc-4.6.2/libexec/gcc/x86_64-unknown-linux-gnu/4.6.2/lto-wrapper
Target: x86_64-unknown-linux-gnu
Configured with: ../../gcc-4.6.2/configure --prefix=/pkgs/gcc-4.6.2
--enable-languages=c --disable-multilib
Thread model: posix
gcc version 4.6.2 (GCC) 

I get exactly the same results as in my initial report.

Do you mean that you get different results with the SVN version of 4.6.2?
