Answer 1

An app is 1 process with N threads. If one thread crashes, the whole app crashes.

In Xcode show the Breakpoint Navigator (on the left). Then click the + at the far-bottom-left and select Symbolic Breakpoint... Finally in the Symbol field fill in malloc_error_break and you're done; run the app again.
