Weird issue: app was working, then starts crashing on launch

[malphigian]

Here's the deal:
-Had a development build of the app we just submitted on my phone, working fine for days (and previous builds worked fine for weeks).

-Yesterday, I touched the app icon, the app launches then crashes out (I wasn't connected to my computer at the time, but if I had to guess, it was around or before when applicationDidFinishLaunching runs). Basically, I briefly see my Default.png, then the app closes. This happens every time I try to run it.

-I restart my phone. No difference, the app is still failing to launch. All other iphone apps I have appear to be working fine.

-This morning I reinstall the app from my development computer and all is well, it's working fine again. No problems. This is the *SAME EXACT CODE* with the same build parameters.

This has me really worried, does anyone have any idea at all what might have happened? It's like the app permanently broke itself, before it even hits any of my code no less . I had a theory it might have had to do with an expired provisioning profile, but I didn't get any message then or when I reinstalled.

I'd appreciate any advice/pointers/ideas people have!.

I've had similar strangeness occur if the provisioning profile associated with the app has expired. Doubt it's the reason; but its one "weird" thing that can cause a crash like this.
