Now this thread is starting to read like an episode of The Big Bang Theory.
One possible guess as to how/why MPICH has managed w/o "volatile" would be that they may pass less aggressive optimization flags to the compilers. It is a then a question of which MPI implementation is supporting a choice of compilers, not a selection of debuggers.

I will therefore propose to forever ban all compiler guys from this time-space, as now we have the undeniable proof that they concoct an evil plan against us. Otherwise, I can't explain how MPICH never had to add volatile to these particular variables and still support all these debuggers… george.
