    I have:
    gcc (GCC) 3.4.4 20050314 (prerelease) (Debian 3.4.3-13.0.0.1.gcc4)
    I have also tried with:
    gcc-3.3 (GCC) 3.3.5 (Debian 1:3.3.5-12.0.0.1.gcc4)
    It made no difference.
    Maybe I'll try vanilla GCC 3.4.4.

    OK, I'll try to minimise my .config.

    Are you sure this is the right .config?
