I did a variety of things, including test whether adding
[Export("initWithCoder:")] affected the behavior of the builds.
My class is a subclass of the class that is inside the .a; the .a has
a binding set built into a .dll. (I'm using the MGSplitViewController
source and bindings from GitHub.)
At this point, while the .a file works fine in simulation builds,
device builds crash with an EXC_BAD_ACCESS (SIGSEGV)
KERN_PROTECTION_FAILURE at (some address) in thread 0. The .a is
being built for the correct platforms, but I'm using Xcode 4 to do
that. I don't see meaningful symbol information in this thread trace,
but I do notice that the thread 0 trace is very long, and that
there's a repetitive pattern in it:
Thread 0 Crashed:
0 libSystem.B.dylib 0x30d05fd4 pthread_mutex_lock + 0
1 bCi 0x00f91954 0x1000 + 16320852

...
508 bCi 0x0100e074 0x1000 + 16830580

Xcode 4 reports that it creates a different .a file for simulation
builds and device builds.
