IOS package crashes in any non-debug compile mode

Question

Hi,
I am looking really for ideas on where to start looking!
This is the situation:
I am migrating a largish flex, web project to mobile. This is the third iteration and I have had the entire thing working at various times in various forms. It loads strings via resource bundle and content via external SWF content.
I have recently reorganised to use a view architecture so that I load in the main app view after a selection workflow - this means that there is much faster startup and better performance in general. It works fine in the following compiles:
1. Compile for Android (all kinds)
2. Compile for iOS debug (fast)
3. Compile for iOS debug (standard)
BUT:
If I compile for iOS ad hoc distribution, I see the following:
1. Initial view loads, resource bundle strings are displaying
2. When I go to main product view:
- SWF fails to complete load process and hangs with no strings from resource bundle visible
- crash occurs prior to addition of navigatorContent buttons that I've defined in the product's base state
In other words, something that works in _all_ other settings and compile options, simply will not progress when packaged for release in iOS.
I am at a bit of a loss. I am aware that iOS can't support bytecode and am working on eliminating that, but I have run it using this with the bytecode simply ignored, which is fine as I don't want it there either. I have also tried substituting for JPEG content, but the issue below still seems to be present. I have also tried eliminating loaded font files - again, these were not working, but the problem was simply ignored when I had the product as the main rather than a sub view.
Does anyone have any idea at all what could be causing this?
Thanks,
G

Got it.
I was using the Swiz framework (which is brilliant, btw) and compiling the Swiz library rather than using the SWC as I needed a change to the underlying, I had omitted one of the metadata tags from the compiler args - for some reason, it recovered when run in any other compile mode, but crashed when run in release mode.
