I've compiled Mono from today's git, and my C# repro doesn't segfault anymore.
In F# interactive, I get "Operation is not supported." too.

With the --trace=N:nothing option, I can see the System.NotSupportedException
is raised twice. The first one is the normal behaviour of F# (it comes from
GetMethodImpl as mentionned by Rodrigo), it also happens on Microsoft .NET and
there is a "catch" instruction.

The second one however is raised in GetMethods, and I think that's the problem.
I got this stack trace with --trace=E:all
