Description Paul DB 2012-08-03 08:58:34 UTC
Trying to compile my app for distribution with the LLVM option enabled fails.
If I turn off LLVM, app builds fine and works on devices.

AOT seems to fail on my class library "MYAPPMobileIOS.dll".  My app consists of the class library project and application project (which references the class lib).

Am using latest Monotouch beta 5.3.5

Build error encountered is:

AOT Compilation exited with code 134, command:
