I have installed Xamarin Studio on another computer this morning. I have fetched my application from a git repository and tried to debug it.
While it used to work fine on my iMAC (2007), now it crashed few minutes after launch on simulator (or device) in debug mode. Attachment is my crash log.
The app first crash on the simulator then Xamarin Studio crash right after.
My iMac is currently running OSX Lion while the Macbook Pro is running Mountain Lion. But my colleague is running mountain lion and have no problem running it
From the log, this appears to be a SIGILL in the GC:

This has been reported as working with Mono 3.0.10, so we can close it when 3.x is released to stable, if it's not fixed in 2.10.x.
The reporter mentioned via email that this happens with Mono 2.10.12 but not Mono 2.10.11, so it may be a regression introduced in Mono 2.10.12.
There are no commits between 2.10.11 and 2.10.12 that could trigger such crash.
How do could I repro this crash?
