[R] segmentation fault - debugging

Hi all,

I'm trying to debug some fortran 95 code that I'm bringing in with a dyn.load().

I'm compiling a number of files using g95 on intel linux w/ R 2.1.0.

The .so file loads without complaint, but when I try to call it I get a seg fault. I was hoping I could get a core dump in order to get some more clues about what is going on, but no luck.

I'm relatively new to fortran programming and have never used gdb before, although
I'm familiar with other debuggers.

Any tips on how to proceed from this point would be appreciated.

Regards,
