Reporting a FREEZE bug

Death Knight:
Hi, My codeblocks (svn) has a bug. It's locking... Than there is no debug output. How can I apply manual debug report? I don't know GDB well. Thank you.

Der Meister:
You should be able to get a backtrace if you follow the following steps:

* Run "gdb codeblocks"
* Enter "r" in the gdb prompt. Code::Blocks should start.
* Do whatever you did to make Code::Blocks freeze.
* Switch back to the console where gdb is running and hit "Ctrl+C". You should see something like "Program received signal SIGINT, Interrupt."
* Enter "bt" in the gdb command prompt. It should print you a backtrace.
* Post the (full!) backtrace here in this thread.
(Note: This works on Linux, I don't know if it works on Windows, too.)

Death Knight:
Hi,
Thanks for code lines, but when Codeblocks freezed, my entire  desktop is freezes.
(it's triggered by Codeblocks, specialy when I select text and move somewhere... )

I can kill codeblocks with CTRL+ALT+F1 (tty1)

You advicing me for running codeblocks with GDB...
I think this not work because GDB has to be started from tty1, isn't it?

Death Knight:
DISPLAY=:0.0 solved my problem, Now I started program, when it freezes I will post debug output here.
I wonder  how can I copy/paste tty window? :
might be running with
gdb codeblocks > debug.txt helps.
Thanks master :)

Death Knight:
I have problem with GDB :(
Program locks most of time when running inside of GDB.
(I compiled this C::B with fress SVN, with also  --enable-debug flag)
