Or is it three? I'm not sure what to make of the "0x0 + 536321".
I don't think this has anything to do with MyFunction, inlined or not. The offsets are huge, much larger than a typical function. Basically, your framework has had its symbols stripped, as is fairly common. So, when the crash reporter goes to correlate an instruction address to a symbol, it finds some unrelated symbol -- basically the closest prior symbol that's still in the binary. In the case of "0x0 + 536321", there wasn't even that much, so it's just an offset from the start of the image. You'll need to symbolicate this.
