Mono devs,

We're more or less tracking Mono trunk on a regular basis, but it seems there's been a regression introduced in 2.7 in the JIT that causes a crash under certain circumstances that makes trunk unusable for us because the runtime aborts when running our unit tests. 

I think what we're seeing is a manifestation of bug 562150 (https://bugzilla.novell.com/show_bug.cgi?id=562150). I've attached a sanitized version of our test case to be bug report in Bugzilla to help reproduce the crash. The crash only seems to appear on 2.7 and not on 2.6.1. The bug wasn't present in r147679, but by the time we updated to 149976 it was, just to give you some context for where the problem might have been introduced.

Any chance someone could take a look at this and see if it's an easy fix? We'd really love to keep tracking trunk, and not keep backporting patches to an old 2.7 revision.
