[Rd] R CMD check seg fault in Linux

It seems the correlation with CMD check and memory was spurious but I have now
observered that the seg faults occur when I run tests on one Linux machine, but
not when I run on the Linux machine I used for installing R (from source) and my
code (which includes some fortan). The machines have similar Linux2.2.9/Mandrake
installations (but fortran didn't get installed on one). The biggest difference
is that the one with fortran installed has has a Celeron processor and the other
one has an AMD-K6. I've never had problems with this differences before. It
might be some time before I get a chance to really dig into it with gdb so if
anyone has any quick insights I would appreciate suggestions. Would there be
compiler flags for different processors or anything like that which might cause
a problem?

Thanks,
Paul Gilbert
