Hi again,
when I call MPI_Init_thread in the same program the error is:
spawning ...
opal_mutex_lock(): Resource deadlock avoided

Really MPI_Finalize is crashing and calling MPI_Comm_{free,disconnect} works!
I don't know if the free/disconnect must appear before a MPI_Finalize
for this case (spawn processes) some suggest ?
I use loops in spawn:
- first for testing :)
- and second because certain MPI applications don't

I believe it's crashing in MPI_Finalize because you have not closed
all communication paths between the parent and the child processes.
For the parent process, try calling MPI_Comm
My C++ is a little rusty. Is that returned intercommunicator going
where you think it is? If you unroll the loop does the same badness
happen?

Hi,
sorry bring this again ... but i hope use spawn in ompi someday :-D
The execution of spawn in this way works fine:
MPI_Comm_spawn ("./spawn1", MPI_ARGV_NULL, 2, MPI_INFO_NULL, 0,
MPI_COMM_SELF, &intercomm, MPI_ERRCODES_IGNORE);
but if this code go to a for I get a problem :
for (i= 0; i < 2;
