crash report using optimization other than -o0 after xcode 4.5 update

Question

I've updated to Xcode 4.5 today and I can't produce a functional release build of my app any longer. I had no trouble producing a release with the previous version of Xcode.

I noticed that it doesn't crash when I run it directly on my phone in debug (-O0), but when I produce a release (-Os) it crashes consistently a few seconds after startup.

I can also produce a working release if I set pjsua_app.c to -O0 while leaving the rest of the project at the release default of -Os.

Below is a crash log using the setting "Fast [-O, O1]":

Can anyone help me diagnose this crash log?

Is anyone experiencing anything similar after upgrading to Xcode 4.5?

Answer 1

I suspect there's a fencepost error on the stack in pjsua_start() or something it calls which leaves the stack mangled when pjsip_init() attempts to return.

Look at the stack pointer, and the contents at the stack pointer, before and after the call to pjsua_start(). On the simulator, this will be the %esp register. (In gdb, you can use "inspect %esp" to show the value or use the register window.)
