Ah -- intel 10. I think you said this before but I blew right past it. I have not personally tested with intel 10; I don't know if anyone else on the team has.

My support guy here at Cisco tells me that he's got a license for it and has been looking for an excuse to spend some time to install them. Hopefully I'll have access within the next several [business] days; I can check it out then. Perhaps we're tripping a problem with that specific version of the compiler (wouldn't be the first time ;-) ).

My systems seem to have that effect on people... :)

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...

5001.0 $ icc --version
icc (ICC) 10.0 20070426

5002.0 $ ifort --version
ifort (IFORT) 10.0 20070426

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.

thanks!,
