It showed up when builds started to use -Wmaybe-unitialized. 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 Thomas
