[Mono-dev] JIT'er bug?
Hello, We are seeing the following stack trace frequently on startup of our application. Seems to happen on both OSX and Linux. We build mono from the 2-10 branch. Any ideas?

Re: [Mono-dev] JIT'er bug?
It does look like a runtime error. Mind filing a bug report with a test case?
