Make sure you don't get a crash report in neither the computer Library folder (/Library/Log/) nor your home Library. You should get a crash report if your application crashes.
Use /Developer/Application/Performance Tools/Spin Control.app to auto sample it when it hangs (use preferences to sample only your app).
And also have a look in Console.app to see if you have some message about your application just before it crashes.

Discussions about tools (compiler, debugger, profiler, …) usually take place on Xcode-users list.
