Thanks for reporting. I have created https://github.com/pmodels/mpich/issues/5744 to track the issue. If you have a chance, could you confirm the issue also exists with the latest MPICH release candidate? http://www.mpich.org/static/downloads/4.0rc1/mpich-4.0rc1.tar.gz

    Dear mpich.org <http://mpich.org>, 
    I was able to compile with gcc 10.2.0.

    Thank you, Doug.

    I apologize.  I sent this email out with the wrong subject matter.  Here is the correct subject.   Thank you.

    I am getting an error installing mpich-3.4.3 on a MacBook Air (M1,2020) with macOS Monterey 12.1, gcc 11.2.0, g++ 11.2.0, and gfortran 11.2.0.  I used the following commands:

    ./configure FFLAGS=-fallow-argument-mismatch --prefix=/Users/douglasdommermuth/mpich2/mpich2-install | & tee c.txt
    make clean
    make V=1 | & tee m.txt 

    I get the following error:

    An online search indicates that others are experiencing this error with gcc 11. For example, here https://github.com/JayDDee/cpuminer-opt/issues/313, https://gitlab.com/xonotic/darkplaces/-/issues/363, and https://github.com/relic-toolkit/relic/issues/202.

    I have not tried an earlier version of gcc.

    Compressed versions of c.txt, m.txt, and config log files are attached.

    Thank you, Doug.
