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.
Thanks for the report and the reproducer. Since you mentioned MPI-IO, I suspect most of the MPICH team will say "Oh, that must be RobL's problem", but I'm (at least partially) off the hook! Your test case doesn't have any call to MPI_File routines. I created https://github.com/pmodels/mpich/issues/3846 to track this defect. ==rob
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,
