Problem with MPICH and Intel and PGI Compilers on Linux

Going on some old memory here, but I seem to remember that the PG
compilers had a switch which allowed specific linking against GNU
libraries. I presume that the Intel compiler has similar options. My
initial guess is that there are ABI differences across the libraries.
If you can set up a machinefile so as to run all the code in multiple
threads on a single machine, you might be able to see this (especially
if you attach a debugger to the process).
The GNU linkage options at least get them speaking the same ABI
(hopefully, as there are differences between 2.96 and 3.x (x<2) and 3.x
See if you can find those option for PG, and Intel. Retry the
builds. See if the error moves.
