Test module which provokes the bug
gm2 hangs if it compiles a module using an opaque type whose implementation
module contains a set. For example see attachment and the following library
files:
DEFINITION MODULE stressset ;
TYPE
dataType ;
END stressset.
----o<----o<----o<----o<----o<----o<----o<
IMPLEMENTATION MODULE stressset ;
TYPE
enum = (red, blue, green) ;
CONST
(* max = ORD (MAX (enum)) + 1 ; *)
max = MAX (enum) + 1 ;
TYPE
dataType = POINTER TO RECORD
next : dataType ;
contents: ARRAY [0..max] OF CARDINAL ;
set : SET OF enum ;
END ;
END stressset.
