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 Gilles
