looks like another duplicate of #64035

My current point of knowledge: The error shows up after updating Xcode 14 to 15 on macOS 13 (Ventura) and sure enough macOS 14 (Sonoma) is equally hit. I tried a series of things to fix this, but did not manage it. At the moment, I see no other way than to limit the port to macOS < 13 and wait until upstream comes up with a solution. #64035 is slightly different but definitely related.

I found that the alignment error results from setting the option -WM13.0. By simply replacing this with -WM11.0 resolves the problem on macOS 13 (Ventura). My latest PR takes care of this. macOS 14 needs a check.

-WM11.0 also fixes it for Sonoma, i.e. macOS 14. Issue can be closed as fixed with version 3.2.2_1.

The build from source was successful. Thanks! Haven't tried to use the Pascal compiler yet...

Thanks for your time and effort! I have successfully used the fpc port for some time now.

Thanks for your feed back. It is so nice that someone else can use the stuff I care for.
