While studying for extending my exception handling hack (exceptions fall through try blocks in threads in a DLL in Linux in fpc 3.0.4) I found these... Unexpected forms in fpc 3.2.0 sources:
raise TObject(nil) at addr,frame;
Raise E at Address,Frame;
Wut.
No mention of any "at" at https://wiki.freepascal.org/Raise
It seems I was Doing It Wrong and my engine was crashing on x86_64 a lot because I didn't know you can raise exception at specific stack frame and do not have to do it... manually via horrifying phtagns?
Checking RunErrorToExcept in the sources of fpc 2.6.4... Yup. Raise E at Address,Frame;. It was always there.
raise TObject(nil) at addr,frame;
Raise E at Address,Frame;
