Rejected twice from iOS app store for crash on startup, but can't repro?

I've written an app using a cross platform SDK (Marmalade) and I have been able to publish a similar app there before. However, after two submissions, the app has been rejected twice for crashing upon startup - something that I cannot repro at all.

I've tested my code loads (especially after the first rejection), and though I don't have an iphone handy, I have sent the signed .ipa to testers to try it for me and they also can't repro the crash (they had to resign, but I doubt this is an issue).

The only major different between my other Marmalade app and this one was the other one was uploaded before arch64 was a requirement. Still, I'm creating builds with ARM + arch64 support. Still, I don't understand why the crash is only being reproduced by the signed distribution version by the Apple team.

I've attached the logs they gave me as I cannot decipher them at all. Specifically:

EXC_BAD_ACCESS

KERN_INVALID_ADDRESS

I've searched online, but it seems to be a pretty mixed bag of solutions, so I have no idea whats up. I've also attached the .ipa I uploaded. Any assistance would be appreciated!
