Comment 3 Marek Safar 2012-06-14 04:20:19 UTC
I think this is a bug in virtual dispatch where wrong method is called
Comment 4 Marek Safar 2012-06-14 05:44:08 UTC
Actually, verifier catches this but why do we allow to call non-accessible method?
Comment 5 Jeroen Frijters 2012-06-14 09:39:33 UTC
We ran into this because an interaction between mcs and ikvm and the current Mono runtime behavior masked the problem. So I would argue for at least reconsidering the choice of not enabling access check by default.
