--- Comment #2 from Stefano Zaghi <stefano.zaghi at cnr dot it> --- A very kind and great Fortraner (Chris MacMackin) has just let me know that a very similar (or really the same) bug has been already reported (60913) here https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60913 Probably my test is slightly more simple. I read that the other bug report is dated 2014: can I conclude that such a bug will need a long time to be fixed? Please, consider that this is not a "polemic" question: I consider all of you my superheros! However, this bug really stops me to use OOP thus I have to decide about my future work: without GNU I have no other compilers, thus if I will decide to invest more on OOP I have probably to left Fortran, probably for Julia... My best regards.
