make -C $GYRE_DIR test on m1 macs

[fxt]

hi everyone,

i have gyre-6.0.1 installed on a variety of intel and m1 macs.
i'm using mesasdk-x86_64-macos-22.6.1.pkg on the intel machines
and mesasdk-aarch64-macos-22.6.1.pkg on the m1 machines.

% make -C $GYRE_DIR test

on the intel machines passes all tests.
on the m1 machines, all tests involving hd5 fail, for example,

TEST numerics (DZIEM variables)...
dataset: </E_norm> and </E_norm>
28 differences found
...failed: summary.h5 and ref/summary.h5 differ

i'm curious if other have seen the same thing on their m1 macs,
or if its my-local-problem, or something else.

thanks!

(realize I never answered this).

This, ultimately, is due to the new gcc 12 compiler that ships with the SDK for MacOS on ARM (M1) processors. The compiler breaks bit-for-bit compatibility with previous compilers, hence the errors.

Importantly, however, they are reproducible and nothing to worry about. So, carry on GYRE-ing on the M1!
