Title: Reporting a FREEZE bug
Post by: Death Knight on November 23, 2006, 09:25:20 pm

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.

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.)

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?

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 :)

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)

This way you won't see the output of gdb but this command should help:

Code

gdb codeblocks | tee debug.txt

Now the output will be printed to stdout *and* debug.txt. ;)

Too bad. Had this message sometimes, too. Did you try to continue with debugging (entering "c" as command)? I think this helped me from time to time.

I assume that is the bug which freezes code::blocks in a drag state of a drag and drop operation. that was a wxwidgets bug which has recently been fixed in wxwidgets2.8 cvs. so for now just be careful when you click on a tab.

Hi,

I don't saw this message, next time, I will be try with "|tee" this...
But I captured freeze time with
>gdb --pid=xxxx > debug.txt
command.
I don't think it will be helpfull. But I needed to send it...

I attached this file.

I am rookie with gdb, I will use 'c' option next time :)

For Kai:
It might be that bug. it happens commonly drag n drop "tabs" and "text selections".
