Ah, ok, now I understand what you tried; thanks.

The above error message is a little puzzling because Open MPI is not providing any -arch flags on the compile command line. But it's the assembler that is complaining (as). Weird.

The source file where the problem is occuring isn't particularly special (ompi/mca/coll/hierarch/coll_hiearch.c). I can't imagine why it would cause this issue. :-\

Try copy-n-pasting the "gcc ... .libs/coll_hierarch.o" command line to a shell and running it in the ompi/mca/coll/hierarch directory and see if you can get it to run. Try snipping out the -O3 and see if that helps. Try removing -fvisibility, etc. See if you can get it to go by selectively removing command line flags.

Other than that, I'm out of ideas. It sounds like it could be either a compiler bug, or some kind of bad interaction between your different compiler / assembler versions on your system...?
