[fpc-devel] Please review bug #41018 in fcl-report (patch added)

[Peter]

Hello,

Can anyone have a look at this bug in fcl-report:
https://gitlab.com/freepascal.org/fpc/source/-/issues/41018

The bug makes using groups with aggregates unusable. The bug also
happens in the included demo in fcl-report.

I think I found a solution and I added a patch. Please review this,
many thanks in advance!

Kind regards,

Peter
