do you get the segfault on the frontend or 
when running on the compute nodes?

hmmmm??? on the XT3 target=linux is a stub.
it is supposed to compile for the frontend but not
for the compute nodes (where you need catamount),
but that actually does not work at all.

i was under the impression XT4 was the same...
