We had some more discussions about this off-list, and Ilya generously
got me a guest account on their cluster in order to replicate the
problem and investigate a fix. Etnus (the makers of Totalview)
confirmed that this is a debugging symbol bug in some versions of gcc,
and recommended a workaround (reordering the order of some #include
files so that struct definitions are not masked).
This workaround is included in the upcoming v7.1.2 of LAM/MPI.
Thanks to Ilya and Etnus for identifying and providing a workaround for
this issue!
