That should be fine with “upstream” sources, should you decide to build from source (but that should not be necessary, there are several places providing gfortran for mac).

I checked the version(s) for which the initialization bug is fixed:

GCC-10.4
GCC-11.3 <<- so you are almost certainly seeing it with 11.2.
GCC-12.1
GCC-13.1
(and current development ’trunk’).

This was a very unusual case - we try to be backward compatible as much as possible, but the change was out of our hands.

So, I’d recommend that you see if your “usual source” has an update - or, alternately, go to one of the ‘OSS distributions’ like Homebrew.

HTH,
