Internal Compiler error with version 19.1.2.258 20200623 (2020.2.258)

[William_Jones]

I have the attached code that now produces an internal compiler error with Intel Fortran 2020.2.258 under Mac OS X.

This code compiles without error under Linux with Intel Fortran 2019.4.243 (19.0.4.243 20190416), and 2020.0.166 (19.1.0.166 20191121) among other older versions.

$ ifort -c reproducer.f90

reproducer.f90(22): catastrophic error: **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.

compilation aborted for reproducer.f90 (code 1)

On windows it is OK

C:\test>ifort -c reproducer.f90

Compiles on Mac if I remove the "bind(c)" attribute from subroutine extra(), but I can't do that in practice.

[William_Jones]

Also, compiles as originally posted with Intel Fortran versions 19.0.3.199 and 19.1.1.216 but not with versions 19.1.2.258 or 19.1.2.279.

Oh and compiles fine with gfortran version 10.2.0

This is all running under Mac OS X 10.15.6.
