gcc 3.4.0 on Linux i686 fails to run R for me

I've just installed gcc-3.4.0 on RH8.0 (on a dual athlon MP, if it
matters) and rebuilt R.  I find interSpline (in example(autoload)) is
failing to complete.  It seems to be looping in dlamc1 in dlapack0.f.
This happened both with ATLAS and the BLAS built in to R.

I will dig a little deeper, but it might be helpful to have a warning on 
record.
