It looks like we do have an errant null pointer dereference here.

Just to clarify, when I say "null pointer dereference":

- you may be trampling over your stack, causing you to pop 0x0 into LR and return there;

- you may be trampling over your stack, causing you to pop 0x0 into a GPR that is then BLR'd to;

- you may be trampling over some other region of memory containing a function pointer, causing you to load 0x0 into a GPR that is then BLR'd to;

- etc.

Cheers, Ash.
