It will be great if you could give us a simple MPI program (not with PETSc) to reproduce this issue.

Hi,<br>
<br>
since more than 2 weeks that the master branch of mpich is still and it can be reproduced with a simple "make test" after a fresh installation of PETSc...<br>
<br>
Is anyone testing it?<br>
<br>
Is it supposed to be working?<br>
<br>
Just tell me if I should "follow" another mpich branch please.<br>
<br>
Thanks,<br>

Hi,<br>
<br>
fwiw, the actual mpich/master branch doesn't passes the PETSc "make test" after a fresh installation... It hangs just afer the 1 MPI process test, meaning it is locked into the 2 process test:<br>
<br>
make PETSC_DIR=/pmi/cmpbib/compilat<wbr>ion_BIB_dernier_mpich/COMPILE_<wbr>AUTO/mpich-3.x-debug/petsc-3.<wbr>8.3-debug PETSC_ARCH=arch-linux2-c-debug test<br>

Using PETSC_DIR=/pmi/cmpbib/compilat<wbr>ion_BIB_dernier_mpich/COMPILE_<wbr>AUTO/mpich-3.x-debug/petsc-3.<wbr>8.3-debug and PETSC_ARCH=arch-linux2-c-debug<br>
C/C++ example src/snes/examples/tutorials/ex<wbr>19 run successfully with 1 MPI process<br>

Hi,<br>
<br>
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>
<br>
Everything was fine (except the issue <a href="https://github.com/pmodels/mpich/issues/2892" rel="noreferrer" target="_blank">https://github.com/pmodels/mpi<wbr>ch/issues/2892</a>) up to commit 7b8d64debd, but since commit mpich:a8a2b30fd21), I have a segfault on a any parallel nightly test.<br>
<br>
For example, a 2 process test ends at almost different execution points:<br>
