It looks like there's a problem with our wrapper compilers on that
platform. This generally means there's something just generally wrong
with the LAM build, as the wrappers are some of the simplest code in
LAM/MPI. Unfortunately, Alpha Linux is not a platform we have access
to for testing. Can you run mpicc under a debugger and see where you
are getting the segmentation fault? It might be helpful to recompile
LAM with debugging symbols turned on, so that there's useful
information in the stack trace.
Good luck,
Brian
