ICE with ifx 2021.3 and LOGICAL*1 variable + debug flag

[Donners__John]

The following test is run when compiling OpenMPI:

program falign
external align
LOGICAL*1 w,x,y,z
CHARACTER a,b,c
common /foo/a,w,b,x,y,c,z
call align(w,x,y,z)
end

This program compiles fine without debug flag: ifx -c conftestf.f

The compiler ifx crashes when compiled with debug flag: ifx -g -c conftestf.f

Hello John,

Thank you for contacting Intel Support.

This is a known issue for our development team and it has already been reported, so we are working on this.

The fix should become available in one of the upcoming releases.

In the meantime, you may use ifort compiler which compiles this code without ICE.

Kind regards,

Khalik.

The problem you reported is fixed in our latest version of Intel® Fortran Compiler (Beta) (ifx) which is part of Intel® oneAPI HPC Toolkit (2021.4).

We will no longer respond to this thread. If you require additional assistance from Intel, please start a new thread.

Any further interaction in this thread will be considered community only.

Regards,

Khalik.
