Xcode 4.3.2 + iOS SDK 5.1 Exception Breakpoint not working

Question

Having Followed these threads:
- Xcode always stopping at main.m after a crash - Xcode 4.2 showing the wrong line of code on error - Debugging app crashes with iOS Simulator & XCode 4 halts in main() function, not crash source

I am still crashing at 'main' as opposed to the actual line of the crash.

• Oddly Works on iOS 4.3 simulator!
• Does not work on iOS 5.1 simulator, or the iOS 5.0 simulator
• I have the exception breakpoint setup and active. (Exception: All, Break: On Throw. Also have tried Break: On Catch)
• Using Apple LLVM 3.1 compiler
• Base SDK 5.1
• Deploy target set to 4.0
• Configuration is set to debug
• Project is ARC enabled
• XCode 4.3

Thanks

Answer 1

Unfortunately lldb is somewhat unstable and appears to be the cause of the crashes in your case. Switching to gdb can cause these crashes to go away.

Try this:

Breakpoints -> Add -> Add symbolic breakpoint. A new window pops up.

Type "objc_exception_throw" in symbol field and click Done.
