mpich configure and make log and preprocessed sources and run script

I've tried compiling the current MPICH release (3.1.4) with Clang 3.6.1. This
led to a segfault of Clang frontend.

Please see attached configure.log, make.log, preprocessed sources and run
script.

Here is the stacktrace and segfault message:
