Thanks Ralph and Gilles! All is looking good for me again. I think all tests are passing again. Will check results again tomorrow.

I just fixed this one - all that was required was an ampersand as the name was being passed into the function instead of a pointer to the name

r32357

Rolf,

r32353 can be seen as a suspect...
Even if it is correct, it might have exposed the bug discussed in #4815 even more (e.g. we hit the bug 100% after the fix)

does the attached patch to #4815 fixes the problem ?

If yes, and if you see this issue as a showstopper, feel free to commit it and drop a note to #4815
( I am afk until tomorrow)

Cheers,

Gilles

Just an FYI that my trunk version (r32355) does not work at all anymore if I do not include "--mca coll ^ml". Here is a stack trace from the ibm/pt2pt/send test running on a single node.
