Whoops, hi Damian, sorry for my late reply. I just saw your mail. I am still hanging ~2000 Fortran-Mailinglist mails back and because you copied the mailing list, your mail got filtered to the mailing list folder and I didn't see it in the vast number or unread mails.

I prepared the gfortran patch to fix exactly the above error, but haven't had the time to fix Opencoarrays, too. I'd rather get a better gfortran-8 up and therefore am trying to get pr81773 and 83606 fixed and get them merged into gfortran-8. I follow this strategy, because gcc release cycles are less flexible then OCs. So as soon as I get 81773 and 83606 fixed, I will come back to OC fixing the type issues. Sorry for the delayed response. My time is very limited and this last gfortran fix involved the scalarizer which is a very complicated concept in the gfortran and I haven't worked with before, therefore a steep learning curve. I hope to be on track more often soon. - Andre > > > Damian > > On February 19, 2018 at 9:32:06 AM, Andre Vehreschild (ve...@gmx.de) wrote: > > Hi all, > > no objections received therefore committed as r257813.
