That fixed it. Looks like something in the latest trunk has triggered
this problem.

I see one difference, and it probably does lead to Terry's cited
ticket. I always run -mca btl ^sm since I'm only testing
functionality, not performance.
Give that a try and see if it completes. If so, then the problem
probably is related to the ticket cited by Terry. Otherwise, we'll
have to consider other options.

Can you tell us how you are configuring and your command line? As
I said, I'm having no problem running your code on my Mac w/10.5,

Yes the application does sends/receives. No, it doesn't seem to
be getting past MPI_Init.
I've reinstalled from a completely new 1.3 branch. Still hangs.

I'm seeing the same behavior on trunk as 1.3. The program just

Well, I unfortunately cannot test this right now Greg - the 1.3
branch won't build due to a problem with the man page
installation
script. The fix is in the trunk, but hasn't migrated across yet.

My guess is that you are caught on some stage where the
hanging bugs
hadn't been fixed, but you cannot update to the current head
of the
1.3 branch as it won't compile. All I can suggest is shifting
to the
trunk (which definitely works) for now as the man page fix
should
migrate soon.

Depending upon the r-level, there was a problem for awhile
with the
system hanging that was caused by a couple of completely
unrelated
issues. I believe these have been fixed now - at least, it is
fixed
on the trunk for me under that same system. I'll check 1.3
now - it
could be that some commits are missing over there.

I have a fairly simple test program that runs fine under 1.2

MacOS X 10.5 . When I recompile and run it under 1.3 (head

They are both built using
--with-platform=contrib/platform/lanl/macosx-dynamic. For
1.3, I've
added --disable-io-romio.
Any suggestions?
