Hi,
I've successfully built openmpi-v1.10.1-140-g31ff573 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 a small
program spawning a process. Everything works as expected with my
programs "spawn_multiple_master" and "spawn_intra_comm". It doesn't
matter if I use my cc or gcc version of Open MPI.
loki spawn 136 mpiexec -np 1 --host loki --slot-list 0:0-5,1:0-5 spawn_master
Parent process 0 running on loki
I create 4 slave processes

-------------------------------------------------------
Child job 2 terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.

mpiexec detected that one or more processes exited with non-zero status, thus
causing
the job to be terminated. The first process to do so was:

I would be grateful if somebody can fix the problem. Please let me

advance.
