FPC 3.2.3 win64, Laz 2.2.0-66 Win64 It was a starter of #39581 - but that minimized example does not exhibit it. ``` SimpleMultiEv.pas(127,1) Error: Internal error 200602034 ``` The error is triggered on the IMPLEMENTATION keyword. The code is crude, but it was intended to be as lo-tech as i can. [SimpleMultiEv.pas.gz](/uploads/329b968d792e3d852bbbc405653ed0c4/SimpleMultiEv.pas.gz) ``` type TSimpleMultiEvent<P> = class; ISimpleMultiEvent<P> = interface ``` This `TSimpleMultiEvent<P> = class;` was a remnant from an attempt, that lead to #39581 discovery. It is not needed. But if you won't remove it - you get another ICE.
