I think I'm having the same issue. See my post: http://forums.codeblocks.org/index.php?topic=3483.0

I'm having this bug occur all the time.

It seems to be when copy from, or pasting to certain places as it will always crash again when I try and copy / paste the same section.

Please make this a priority as CB is now crashing atleast ~10+ times an hour

Sorry, failed to mention im using Linux (ArchLinux specifically), GCC 4.1 with gcc 4.1 compile fix mentioned in the forums.

Although previous versions that didn't need the fix still had this copy/paste crash bug.

Also, the CB feedback agent that usually runs during crashes, did not run for this crash.

Does this bug still persist?

I'll check if it still persists in the current version over the next few days (no spare time atm)

Same problem with me. Linux SuSE 10.1, gcc 4.1, wxGTK 2.6.3, CB rpm rev 3202. Some combinations of text crash consistently when Ctrl-C or Crtl-X

I also have the same really annoying problem... 


I'm on archlinux, build from today revision (3218), with old build (3081) same problem.

Some specs if  more needed I'll post again:)

I can reproduce this bug. Codeblocks crashes everytimes when I copy a piece of code of 12+n*8 character length.

svn version: 3500

OS: Redhat

Was partially built with older libraries

I'm encountering this bug on svn build rev 3496 (2007-01-16 19:06:00) gcc 3.4.6 Linux/unicode.

Occaisionally when I paste a line of text codeblocks closes.

*** glibc detected *** free(): invalid next size (fast): 0x08ce1fb8 *** Aborted

Code::Blocks is awesome but this bug is bad news I'm afraid to use it now because I keep losing work.

Slackware 11 with 2.6.17.13 kernel on x86.

OK, just to make sure, is everyone having this issue using wxWidgets with the latest patches from:

http://wxwidgets.org/downloads/patch.htm

I have applied the patches and rebuilt and have not seen the problem since. I would say it is greatly mitigated or fixed. Thanks mike_t for the info and arto_j for the followup. Great app and great team.

Closing it based on user feedback.
