[patch, fortran, committed] Fix PR 80162, warning about missing location information

[Thomas Koenig]

Hello world,

I have committed the attached patch as obvious and simple
after regression-testing, as rev. 246388.

This is a case where the location checking pass did its job
and found a place where the location information was indeed
missing.

Regards

        Thomas
