I'm embedding MonoTouch's mono library in an objective-C iOS project, which
is working fine for basic stuff like creating instances of .NET objects,
calling methods and setting properties via the embedded mono C API.
When I try and use my large .NET assembly, however, I seem to be getting a
SIGBUS signal on a garbage collection thread. I can't work out from the
stack trace (pasted below) why this is happening. Any suggestions for how
can I debug this?
Thanks.
