A scan of gcc/fortran/ChangeLog shows a number patches that tinker with the character length for deferred length strings. I don't which one is the responsiblei, and since I don't use git (other than for trivial 'git diff' and 'git pull') doing a bisection is beyond my skillset. Someone should likely convert your testcase into something that the testsuite can digest, and commit it.
