Hi everyone,
this guy has the same problem..
http://stackoverflow.com/questions/5084475/monotouch-nullreference-for-every-event-action-sigsegv
Now I've built a view which listens to events from a Monotouch Library. The
SIGSEGV error also appears but only after it worked a little bit in the
library. Otherwise it works correctly....
It really seems that the Garbage Collector disposes my objects.... What can
I do?
Should i make an example project for you guys?

[MonoTouch] Antwort: Re: Antwort:
Re: Re: App crashes randomly when
hitting UIControls
Hi Rolf,
Thank you for your reply.
I've posted the output of my device in my first post.
>>> The console off my device shows the following:
>>>
>>> Stacktrace:
>>> at MonoTouch.UIKit.UIApplication.Main (string[],string,string)
>>> <0x0010f>
>>> at myApp.Application.Main(string[]) [0x00000] in
>>> /Users/me/Projects/myApp/myApp/Main.cs
>>> at (wrapper runtime-invoke) object.runtime_invoke_dynamic
>>> (intptr,intptr,intptr,intptr) <0xffffffff>
The debuggers jumps not into the breakpoint, because the error appears
before. It's not even jumping in CodeBehind.
Maybe that's a help for you, the error appears often with the SIGABRT and
SIGSEGV errors.
Best regards,
Sebastian Kellner

UIControls
Hi Sebastian,
You should be able to find crash logs for the crash (in Xcode's
Organizer for device crashes and in the Console application for
simulator crashes). Can you attach one of those? And can you put a
breakpoint on Cancel_TouchUpInside to see exactly which instruction is
causing the crash?
