I think this is OK for trunk now, and backport for up to whenever
-Wmaybe-uninitialized was introduced into the build.

The "regression-only" rule is mostly motivated by not introducing
new bugs (and for Fortran, we have a bit of leeway), and I would
be hard to pressed to think of a patch less likely to introduce
regressions.

Thanks for the patch!

Best regards
