Hal,
I rebuilt the opensm executable with the patch you provided. The patch
fixes (or avoids) the segmentation fault and opensm comes up and runs.
However, the link is still not becoming operational. On the local side
it goes to ARMED, and on the remote side it goes to INIT. The osm.log
seems to show that the MAD packets are timing out. Here is the first part
of the file, it just repeats after this at one minute intervals.
