Subject: [OMPI devel] yesterday commits caused a crash in helloworld with --mca btl tcp, self

Folks,

a simple
mpirun -np 2 -host localhost --mca btl,tcp mpi_helloworld

crashes after some of yesterday's commits (i would blame r31778 and/or
r31782,
but i am not 100% sure)

/* a list receives a negative value, so the program takes some time
before crashing,
symptom may vary from one system to an other */

i digged into this, and found what looks like an old bug/typo in
mca_bml_r2_del_procs().
the bug has *not* been introduced by yesterday commits.
i believe this path was not executed since yesterday, that is why we
(only) now hit the bug

i fixed this in r31786
