 Replying to [comment:19 michaelld]:
 > Building gcc12 at the moment, and then I'll finalize testing. I
 ''think'' the issue is that when using `+gfortran` the C/C++ compiler is
 AppleClang -- the Clang installed by Xcode, which for 10.14 the most
 recent is `Apple clang version 11.0.0 (clang-1100.0.33.17)` -- and
 AppleClang is notorious for not about feature set support correct. I
 ''think'' with `-gfortran +gcc*` we use GCC for all compilers, and GCC is
 much better about getting feature set support correct. If I'm correct then
 blocking use of specific AppleClang is the way to go for MP needs. NumPy
 should add better testing to verify feature set support, but that's
 outside the scope of what I am reasonably going to do. More soon!

 I have tried to use +gcc10, +gcc11 and +gcc12, but could not build anyway.
 Do you need log for these builds?
