13.0 compiler ICE

13.0 compiler ICE

Compiling the attached tiny example as-is in two separate files results in an internal compiler error with 13.0: intel-bug-20121006b-2.f90(4): 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.

The example compiles fine if the source is consolidated into a single file.

I have escalated this issue to the developers. The issue number is DPD200237121. I will post any updates I receive to this issue.

It does not occur when the program and module are in the same file because the subroutine call is optimized away unless it is compiled with optimization turned off (-O0).
