Eric, adding those flags worked. Thanks!
<div class="">Rob, yes, bug report from libressl matched with what I was getting. </div>

<div class="">Can you please explain what was wrong? I installed the GNU compilers using Homebrew. I realize I should have used “brew link gcc5” or something, but instead, I went to /usr/local/bin and manually created the symlinks (gcc, gfortran, g++, etc)
pointing to gcc-5, gfortran-5, etc. Did I miss something?</div>
<div class=""><br class="">
</div>
<div class="">I did not face this issue when I did the same thing (Homebrew gcc + compile MPICH + manual symlinks) on a Macbook. The only difference I see there is that the build is apple-darwin14.4.0.<br class="">

We test with gcc-5.2 on our mac build bots, so it's definitely possible.<br class="">

When the assembler is suspicous ('movq') then it sure seems like there's a<br class="">
toolchain mismatch.<br class="">

Does this bug report from libressl sound like your environment?<br class="">
