Debugger g++/gdb

Test	Result	Annotation
Create new project. Can you build, run and debug it?	automated
Set breakpoint, press F5 to build and run debugger, verify that program stops at a breakpoint that you set: in main function before program is started while the program is running in dynamically loaded plugins, especially in constructors on a bit of code that was commented out. Make sure it is moved on debugger startup to the first line producing real code below that position and that it is hit there.
"Step into" a couple of times. Can you step into Qt source code (*.cpp file under QTDIR)? (Mac: switch on 'Use Debug Versions of Frameworks' in run configuration. You need Qt sources.)
Test debugging helpers/python gdb: Do classes like QImage or std::string show beautiful information instead of the raw structure?	automated
Step through some test* functions and check whether the displayed data looks sane
Comment out the return statement inside the following functions one by one. Check whether you'll end up with a proper stack trace & locals display. testNullPointerDeref() testNullReferenceHelper(pp, qq); testEndlessLoop(); (break manually) testEndlessRecursion(); testUncaughtException(); (not on Windows)
Switch on temporarily 'Operate by Instruction' and check whether you see disassembler output and can step by instruction
Check I/O (qDebug, std::cout, std::cerr), on Win for both Debug and Release. Please read the below note!
Check "Run in Terminal". Use Terminal for input. (Debbuging might not work on Ubuntu)
Check nothing bad happens on a simple int main() {} program with no breakpoints set	automated
Linux/Mac: Attach to a core file (ulimit -c unlimited)
Attach to a running process (might not work on Ubuntu)
Test unusual situations: Kill the running debugged program 'externally' with a signal that is neither SIGSTOP nor SIGKILL. Qt Creator should end up showing a backtrace.
Kill the stopped debugged program 'externally'. Nothing should happen immediately, on next continue or step Qt Creator should end up showing a backtrace.
Kill gdb externally. Qt Creator should notice the gdb process ended and show a message box.
Try remote debugging: start a gdbserver using e.g. gdbserver localhost:1234 ./fakevim in creator/tests/manual/fakevim on a Linux machine and connect to it

stderr/stdout handling on Windows

• An application needs to be built with 'console' for stderr/stdout to appear (use Creator's "Run in terminal" setting)
• Creator itself is built with 'console' in debug mode only.
• qDebug() prints to stderr for ‘console’ apps, else to the Windows debugger log, which can be shown with the DbgView utility
