[mpich-discuss] mpich/master: Something got wrong since may 24

Hi, I am in the early debugging stages of something that broke on may 24 on our test database with 17 tests against mpich/master branch. It seems related to MPI I/O, since we have observed the bugs just after MPI I/O reads. Everything is fine with other MPI libs, even older mpich. This is only a mpich/master problem. My early query: am I alone to have observed this? Thanks, Eric
