I've looked for the answer to this several times and never found anything: Is there any way to get any sort of useful information as a result of an "assert" failure, either on the emulator or on the hardware? The popup message shows you the name of the application and the first 5 characters of the failing test, which is not a great amount of help. And with all but the C++ exception traps enabled on the emulator, enabling those traps catches nothing. (The C++ trap, of course, catches every 3rd instruction.)
With Qt I can put a stop at qFatal, but I haven't found the equivalent for native assertion failures.
