Mark,

Thanks for the toy program. I could reproduce the problem locally. We 
also experienced a similar bug with a PathScale compiler. We are still 
working on a fix, though. You can follow the progress and potentially 
provide more input in the ticket I created to track this issue 
(https://trac.mpich.org/projects/mpich/ticket/2350).

Regrading missing symbols from dynamic libraries when using gdb on Mac 
OS, I personally never managed to make it work, not just with MPICH, but 
also with other libraries. I consistently do static builds to avoid this 
problem. If you are able to see symbols from other libraries, we might 
want to look into this as well.
