I have an application that can be minimized to uiscrollviews with images that you can scroll through. However, I am experiencing something really strange.
When you view each image (there are about 60 in total), at some point the application simply terminates. I run it in Xcode 4 (GM seed 2) and I do not receive debugging information and no messages in the console at all. NSZombieEnabled is included, but that hasn't changed anything.
I don’t even have a crash log on the device. I run it with the tools and it does not report any leaks, and the use of my memory is from 700 to 1100 KB when run on the device.
I even checked each of my “pages” (the ones you scroll through), and added the messages to init and dealloc, and I can confirm that they are all freed up properly (just keep the current one and the pages on each side are loaded).
Now this seems to be mainly happening in the same place in the application, when I just start from the very beginning and look at every page going to the right, plus or minus several pages, all indicate a memory problem, I get a memory warning from the device, but there is absolutely nothing that would indicate that I use a lot of memory in general, and that there are any leaks.
I got this from the console on the device when the application shuts down:

Now this mentions a crash report, but how can I hold it when it doesn't show up in Organizer in Xcode? And why do I get memory warnings when the tools (and a careful look at my code) say that I don't use a lot of memory or leakage?
Help!
EDIT: Now you can run 3.6 and run the console here:
