Unexpected "warning #7026: Non-standard extension" for a parameterized derived type with type-bound procedures.

[FortranFan]

This builds on the code snippet in Quote #2 in the topic:  https://software.intel.com/en-us/forums/topic/536577.  Compiler 15, Update 1 gives "warning #7026: Non-standard extension." with /stand:f08.  To me, this is unexpected.  Comments?

We've seen this one before - I'll check it out in more detail on Monday.

I believe that any standards warning here is unwarranted. We have other reports of this diagnostic coming out for uses of PDTs. I have escalated it as issue DPD200363879.

[Steven_L_Intel1]

I expect this to be fixed in Update 2, planned for February, as part of a set of fixes for PDTs.

Excellent news Steve.  I look forward to the update.

Thanks,
