Description renan jegouzo 2014-08-26 03:33:58 UTC
I have an application that works well, but if I send it in background, it crash when coming back foreground.
with this error in the organizer console:

<Error>: objc[399]: autorelease pool page 0x172b6000 corrupted
	  magic 0x00000000 0x00000000 0x00000000 0x00000000
	  pthread 0x0

It wasn't happening before, I think it's one of the last Xamarin update who added that.
I have no unsafe code in this project.
