IFX internal compiler error when using function pointers

[SamvanderZwan]

I am switching from ifort to IFX when I had the following error:

Severity Code Description Project File Line Suppression State Details
Error error #5623: **Internal compiler error: internal abort** Please report this error along with the circumstances in which it occurred in a Software Problem Report. Note: File and line given may not be explicit cause of this error. C:\Users\zwan\source\repos\Console1\Console1\test.f90 25

I manged to reproduce the error in a small project fortran code files attached.

If this is compile with the Check routine interfaces set to no it gives this error, when the routine interface check is switched on it will compile.

It also compiles when you copy the subroutine into the main code even when interface check is off.

I am using VS2022.

I was wondering if this is a known issue.

@SamvanderZwan, I was able to reproduce the issue internally. Thank you for your report. This case has been escalated to compiler engineering for a fix.
