Please file a bug report for the issue at http://trac.mcs.anl.gov/projects/mpich2/newticket.

If you have a small test program that we can use to reproduce the problem, that will be helpful and will increase the chances of getting the bug fixed sooner.  Please also note whether it is happening only when you actually are attached with the debugger or if it will also happen without the debugger's involvement.

We'll take a look at it as soon as we reasonably can, but I can't make any promises that it will be fixed very soon.
