Yes, this is caused by a bug on the Tru64 compiler that was supposed to be
fixed in version 5.2. I'm not sure what the status is, but we've put
together a quick patch that should workaround any versions that have this
problem. You can download a trial version of the patch now from
http://flash.uchicago.edu/~siegela/CompaqPatch.tar

We are still a few weeks away from fully testing our code on a Compaq
cluster. Until then, I can't gaurantee that this patch will solve all of
the Compaq problems. It certainly works around the one you point out, but
it's possible there are others. In several weeks, we will be running our
full test suite nightly on a tru64 cluster. In the meantime, this is all
we can offer.

To run the patch, copy the .tar to your $FLASH_HOME directory. Then do

tar xvf CompaqPatch.tar
./runpatch

Please let me know of any problems.
