Looks like the same source tree was used cleaned (distclean). So I
don't have config logs for gcc or pgi.. Also I can't find
opal_confg.h in ether the configured/built source or installed
location,
1.2.8+pgi, This library was found to run an executable built with
1.2.6+gcc
Sorry I don't have the files you requested George.

Black magic happens all the time. To keep it simple, we do not
expect different compilers to be 100% compatible, so this is
completely unsupported by the Open MPI community. Moreover, we
already know some compilers that claim gcc compatibility, when
there are always some [obscure] things that don't really match
(hint icc and gcc).
For Fortran there are even more issues. One was already hinted in a
one of the answers (logical), but more are expected such as the
representation of the "strange" type REAL16 and REAL32 (and the
corresponding COMPLEX types). I'm sure more can be found, but these
are enough not to support the cross-compilers stuff.
Now, I'm really curious that this worked. Do you have access to the
opal_config.h file for the pgi and gcc build ? Or to the config.log
files ? If yes can you share it with us please.
Thanks,
george.

if anyone has had problem with it.
At runtime. (not compiling) would a OpenMPI built with pgi work
to run a code that was compiled with the same version but gcc
built OpenMPI ? I tested a few apps today after I accidentally
did this and found it worked. They were all C/C++ apps (namd and
gromacs) but what about fortran apps? Should we expect problems
if someone does this?
I am not going to encourage this, but it is more if needed.
