Could you please try the latest MPICH 3.3b3 tarball or clone the MPICH master branch at
<a class="moz-txt-link-freetext" href="https://github.com/pmodels/mpich">https://github.com/pmodels/mpich</a> ?<br class="">
<br class="">
If you still see any failure, please send us the config.log file at your MPICH build directory, and a simple reproducer program.
<br class="">
<br class="">
Thanks,<br class="">
