Fortran code demonstrating problems.

Hi All!

ICE with 10 and 11 on assumed-rank character array with select rank block.

using:

GNU Fortran (GCC) 10.1.1 20200518
GNU Fortran (GCC) 11.0.0 20200518 (experimental)

This is very likely related to Bug 67938 and Bug 66833.

Thank you very much.

Best regards,
José Rui
