[geir]

Beginning with Intel OneAPI 2025.1.1 for Linux, the following error occurs:

/tmp/ifx1218407474hdxmCL/ifxCZO9Il.i90: error #5633: **Internal compiler error: segmentation violation signal raised** 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 cmp.F90 (code 3)

Problem fails when -O2 or higher is used, and works for -O1 or lower.

Compiling with Intel 2025.0.0 works fine.   

Here is the failure:
