Description Gerd Behrmann 2006-03-08 20:58:51 CET 
It seems that the type checker does not catch an assignment to an identifier used in a selection expression on an edge, i.e.

select i : int[0,3];
assign i = 2;

does not give a syntax error. Instead, the verifier throws an exception.
Comment 1 Gerd Behrmann 2006-03-09 21:42:02 CET 
Quantifiers suffer from the same problem. Iterator statements to not cause an exception but a runtime failure during verification.
Comment 2 Gerd Behrmann 2006-03-10 12:52:02 CET 
Fixed on the trunk.
