A wrong column is selected when addressing individual elements of unlimited polymorphic dummy argument

A wrong column is selected when addressing individual elements of unlimited polymorphic dummy argument

[Gayday, Igor]

Hello,

Please, consider the issue described here:
https://stackoverflow.com/questions/63841012/a-wrong-column-is-selected-when-addressing-individual-elements-of-unlimited-poly

I believe this is a gfortran bug. I tried it with gfortran 10.2 and it still happens. The same program works as expected with ifort 19.0.3.199.

Sorry for not using bugzilla for this, but the form did not work and I didn't get a reply regarding account creation.

Best regards
Igor Gayday

Hi Igor,

class array support has some deficiencies in gfortran. See for example:

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78466 or
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96992

Your Fortran look reasonable to  me and you could have found another bug.
Please continue to try to file a bug in the official bugtracker or your finding
may be lost.

Thanks for your help and regards,
	Andre

Hi Igor,

I identified two separate bugs that cause this problem. I am away on a trip
until Sunday and will implement a fix then.

Thanks for the report - could you file it in Bugzilla, please?
