Hi Pierre,

Thanks for your info.

Note, I have raised a bug report for this crash now.
https://gitlab.com/freepascal.org/fpc/source/-/issues/40177

Given that -fpic is unsupported on m68k,
perhaps the compiler could abort an attempted -fpic compilation there with a meaningful error message,
rather that crash out with an internal error?

Cheers,
Peter
