I'm quite sure, actually (though I only took a quick glance at them)! :-)

(It'll be interesting to see if gpc's adopting other features can keep pace with new Pascal dialects being developed... ;-)

Schema discriminants must be ordinal types, but the following compiles:

Type
   roots ( p, q: Integer )
     = array [ 1..1 + ord ( sqr ( p ) / 4 - q <> 0 ) ] of Complex;

However it is useless since

Var
  x: roots ( 4, 4 );

crashes GPC.

That's what I meant with my "bug report". I didn't check if the type or the var declaration caused the internal error.

I just found another bug -- or is it an instance of the "cannot write longint variables" known bug?

var c:cardinal value $ffffffff; begin writeln(c) end.

...writes -1.
