I'm on Mono 2.10.3, MD 2.4, MonoTouch 4.0.4.1, on Lion.

Getting SIGSEGV crashes regularly using iPhone Simulator when just typing
into UITextFields, also a ShouldReturn delegate call to ResignFirstResponder
to close keyboard crashes every time.

Have tried numerous versions of Mono, MD, and Monotouch, but same issue on
all...basically wish I'd never moved to Lion :(


Here's the output...
Error connecting stdout and stderr (127.0.0.1:10001)

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
