Walter Bright <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |[email protected] --- Comment #3 from Walter Bright <[email protected]> 2010-05-09 17:56:02 PDT --- Thanks for the reduced test case. This is a rather nasty problem. The essence of it is that when the is(T.__isQObjectType) is evaluated, T is forward referenced. So it attempts to forward instantiate T. This fails, and so the IsExpression fails. The problem is that in the attempt to forward instantiate T, it doesn't quite reset itself back to the state it was in before the IsExpression, and now parts of the symbol table are in an "error" state, and a cascaded error message (hence incomprehensible) comes out as a result. A workaround is to remove 'abstract' from the class declaration, which enables the forward instantiation to succeed. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
