[OMPI users] funny SIGSEGV in 'ompi_info'

[Paul Kapinos]

Dear developers,
also the following issue is defintely raised by a misconfiguration of Open MPI,
SIGSEGV's in 'ompi_info' isn'n a good thing, thus this one mail.

Just call:
$ export OMPI_MCA_mtl="^tcp,^ib"
$ ompi_info --param all all --level 9
... and take a look at the below core dump of 'ompi_info' like below one.

(yes we know that "^tcp,^ib" is a bad idea).

Have a nice day,

Paul Kapinos

P.S. Open MPI: 1.10.4 and 2.0.1 have the same behaviour
