Ralph,
I got consistent segfaults during the infrastructure tearing down in the
orterun (I noticed them on a OSX). After digging a little bit it turns out
that the opal_buffet_t class has been cleaned-up in orte_finalize before
orte_proc_info_finalize is called, leading to calling the destructors into
a randomly initialized memory. If I change the order of the teardown to
move orte_proc_info_finalize before orte_finalize things work better, but I
still get a very annoying warning about a "Bad file descriptor in select".
Any better fix ?
George.
PS: Here is the patch I am currently using to get rid of the segfaults
