I don't think that the output is of any use. The output of "scons" would
have been better, but fortunately I already know what the problem is.

This is because you are have enabled SIMD on a compiler where SIMD is
buggy (gcc 3.3.x).
Either do "scons simd=0" or figure out how to keep the essential SIMD
stuff enabled while disabling it for the 95% of the code for which it
doesn't matter as much... I haven't tried the latter because I haven't
really learned scons. Other people would urge you to upgrade to GCC 4.0 or
4.1.
I tried installing GCC 4.0.2 manually which kinda works, but GCC 4.0.x
doesn't want to compile some other program that I really need and it turns
out that the way I've installed it, GCC 3.3.x doesn't work anymore because
of a conflict of libstdc++ versions that I don't know how to fix. So I
completely reverted to GCC 3.3.x.
