Howdy,

Apparently the gcc folks have been busy, tightening up the "rules". I'm not sure this isn't one so I'm reporting it.

Best regards,

George...

This is output from gcc (GCC) 15.0.1 20250325 (experimental) but the non-experimental version shows the same output.

It's not a bug in grep. We pacified GCC's false alarm in grep commit 
08c4ce064b7f42acc023a9b28d1076a81feb6143.
