EXC_BREAKPOINT (SIGTRAP) is a trace trap interrupted the process. It gives an attached debugger, if any, a chance to interrupt the process at a specific point in its execution.
EXC_BREAKPOINT (SIGTRAP) and EXC_BAD_INSTRUCTION (SIGILL)A trace trap gives an attached debugger the chance to interrupt the process at a specific point in its execution. On ARM processors, this appears as EXC_BREAKPOINT (SIGTRAP).
The SIGTRAP signal is sent to a process when an exception (or trap) occurs: a condition that a debugger has requested to be informed of — for example, when a particular function is executed, or when a particular variable changes value. Indeed, debuggers use this signal to set their breakpoints.
You can also turn on Exception breakpoints. In XCode 4 click your project and choose the breakpoints tab. At the bottom of that tab is | + | - | search bar. Choose the + item and "Add Exeception Breakpoint". You can leave it at All or choose Objective-C. This way you will break in the debugger and be able to see what caused the exeception.
