Problem still exists with
euler-18% /pkgs/gcc-mainline/bin/gcc -v
Using built-in specs.
Target: x86_64-unknown-linux-gnu
Configured with: ../../mainline/configure --enable-checking=release
--with-gmp=/pkgs/gmp-4.2.2/ --with-mpfr=/pkgs/gmp-4.2.2/
--prefix=/pkgs/gcc-mainline --enable-languages=c
--enable-gather-detailed-mem-stats
Thread model: posix
gcc version 4.4.0 20080708 (experimental) [trunk revision 137644] (GCC)
Just checking whether recent changes happened to fix it.
