As you can see, I can either Wait(and it eventually bring me to the same screen) or Force Quit the generated debug-mode theide which end the generated debug-mode theide completely,leaving me no chance to check the call stack.

[code]

Times like that you pretty much have no choice but to run gdb directly and get a call stack.

gdb <appname>
run

then when it crashes type bt for a backtrace
quit (or q) to quit.

I'm not an expert with gdb but it could get you further. It has a help section, a tui (if you run it with -tui) and I think they even added python scripting support a while ago.

You can post the backtrace here...
