An ICE with ifort (IFORT) 2021.5.0 20211109 using coarray=shared compiler flag

[jdelia]

Dear developers,

Apologies in advance because I'm a new user in this forum and I don't know if this is the right place to report a Software Problem Report.

Below there is a simple session with a reduced test case (please see attached file) that produces an Internal Compiler Error (ICE) with the ifort compiler using Fedora 35 on a x86_64-pc-linux-gnu machine, but it is ok with the gfortran one.

Regards.
Jorge.

Thank you for reporting this ICE. I filed a bug report on your behalf, CMPLRIL0-34546. I'll let you know when it's fixed.

Dear Barbara: ok, I will look forward to hearing from you when it is fixed. Thanks! Regards. Jorge.

This ICE is fixed in the Fortran compilers, ifort 2021.7.0 and ifx 2022.2.0, that were released earlier this month. Both compilers are available as part of the oneAPI HPC Toolkit.

Give it a try!
