Siegmar,
the fix is now being discussed at https://github.com/open-mpi/ompi/pull/1285
the other error your reported (MPI_Comm_spawn hanging on an
heterogeneous cluster) is
being discussed at https://github.com/open-mpi/ompi/pull/1292
Cheers,
Gilles

Hi,
I've successfully built openmpi-v2.x-dev-958-g7e94425 on my machine
(SUSE Linux Enterprise Server 12.0 x86_64) with gcc-5.2.0 and
Sun C 5.13. Unfortunately I get a runtime error for all programs
if I use the Sun compiler. Most of my small works es expected with
the GNU compiler. I used the following command to build the package
for cc.

It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_INIT; some of which are due to configuration or
environment
problems. This failure appears to be an internal failure; here's some
additional information (which may only be relevant to an Open MPI
developer):
ompi_proc_complete_init failed
--> Returned "Not found" (-13) instead of "Success" (0)

I would be grateful if somebody can fix the problem. Please let me
know if you need anything else. Thank you very much for any help in
advance.
