EXC_BAD_ACCESS (SIGSEGV) crash

Question

How do I trace the crash ?

Process:         iAddressGrabber [253]
Path:            /Users/egrabber/Library/Application Support/iPhone Simulator/User/Applicat         


        

Answer 1

Enable NSZombie - it will tell you which de-allocated object objcMsgSend is trying to call.

See this earlier question.

Answer 2

The following technical note contains all the information needed to deal with such dumps:

Technical Note TN2124 - Mac OS X Debugging Magic

A little hint:

1   CFNetwork                       0x006b4868 URLConnectionClient::_clientDidFinishLoading(URLConnectionClient::ClientConnectionEventQueue*) + 194

Focus on this part, the EXC_BAD_ACCESS suggests a (ab)use of invalid memory pointer.
