This is with mono master and 3.2.7 branch.
Comment 1 Miguel de Icaza [MSFT] 2014-02-11 12:28:57 UTC
That is not really a problem with wildcards, since mono itself never receives a wildcard.

The above is a crash in a specific assembly.   So we do need to identify which assembly is causing this crash.

Hello,

Can you still reproduce with latest mono? If so, could you please provide the assembly on which it is crashing?

Thank you
