Our app is using a custom split view controller that we're getting rid of for
the next major release, but for the CURRENT release we still have it. The
problem I have is that on iOS 9 we're seeing the above when we hide the master
view and show it a few times over and over agian.
Its random where it ends up crashing, but it always EXC_BAD_ACCESS. So…I fire
up Instruments and Zombies…no issues. Does not crash. I try it with Runtime
address sanitization, and finally the regular stuff. When using the any of the
above - it does not crash ever. When turning it off (and of course running in
Release mode), it crashes after a few tries.

I'm quite sure its my bug somewhere having to do with memory…but I'm at a loss
where to move forward with this. I'd love some ideas…
