If general C++ applications seem to be working with icc/icpc, I do not know why OMPI would fail for you with icc/icpc (especially while accessing stack memory). What version of icc/icpc are you using? There were some bugs in the 8.x series that caused problems, IIRC...

Do the intel compilers come with any error checking tools to give more diagnostics?
yes, they come with their own debugger. I'll try to use it and send more info when done.
