<p>Hi,</p>
each night we are testing mpich/master with our petsc-based code. I
don't know if PETSc team is doing the same thing with
mpich/master? (Maybe it is a good idea?)<br>
<p>Everything was fine (except the issue
<a class="moz-txt-link-freetext" href="https://github.com/pmodels/mpich/issues/2892">https://github.com/pmodels/mpich/issues/2892</a>) up to commit
7b8d64debd, but since commit mpich:a8a2b30fd21), I have a segfault
on a any parallel nightly test.</p>
<p>For example, a 2 process test ends at almost different execution
points:</p>
<p>rank 0:</p>
