It is really not related to specific lines. But sometimes the error will repeat a lot on some lines.

Please, can you confirm if a zip file containing the project it self is a minimal valid example? (I am afraid that changing the trying to simplify the project will "solve" the error).

With some more specific instructions, I can try to figure out how to build an as minimal as possible example.

Best,
R

This is not always trivial because the internal errors are sometimes quite fiddly. I have a project in which an internal error occurs sometimes. When I do a "cleanup and build" (in Lazarus), it works well. There seems to be an influence of the order in which units are compiled, because I can change code in many places without getting the internal error again. But when I change code in other units, I get the internal error, but it's clearly uncorrelated to the line at which it occurs. ------------------------------ Message: 2 Date: Sat, 21 Oct 2023 22:25:45 +0200 From: Sven Barth To: FPC-Pascal users discussions Subject: Re: [fpc-pascal] Error: compilation raised exception internally Message-ID: <CAFMUeB8azQR1k6HMckxWQ82eMgavEvzZk4yZD= > Content-Type: text/plain; charset="utf-8" Thomas Kurz via fpc-pascal schrieb am Sa., 21.
