I'm sorry to disappoint you, but there simply is no roadmap and I'm not able to
provide one. That's just not how things work with gfortran.

If you absolutely critically depend on some feature being available in a
certain time-frame, then your best options are probably:
a) Try to implement it yourself or
b) pay someone to implement it.

I don't think the bug is incredibly difficult to solve. I already have a basic
understanding of what's missing (see my analysis above) and I might look into
fixing it soon. BUT: I simply can not give you any roadmaps or guarantees for
that.

And yes, gfortran could definitely use some more manpower. If you are willing
to help (or know someone who is), you're certainly welcome.

Sure, that will probably help to understand the problem. Thanks for your
efforts.
