I have found the problem, and described it in

The problem is comparison for equality between doubles. In my case, for the event I was debugging, they were exactly equal in sequential mode, but equal only to 14 significant digits in MPI mode.

I believe that the flakiness of this coding error can explain the curious symptoms I found. Moreover, fixing line 168 in made the problem go away.
