Comment 1 Jens Dagerbo 2006-12-17 02:34:01 UTC

What KDevelop version did you use? Can you test with 3.4 branch?

Comment 2 Sergei 2006-12-17 04:14:32 UTC

3.4 branch is the same.

Comment 3 Andreas Pakulat 2007-01-14 22:17:32 UTC

Please try to capture the debug output from KDevelop. Start kdebugdialog and deactivate everything except number 9007 (cpp support). Then run kdevelop from a shell and redirect standard output and error output to a file like this: kdevelop >file 2>&1. If its not too large post the whole file, else just post the last 40 lines or so. This tells us and you which file is beeing parsed before the crash. Then if its possible attach the file to the bugreport too.

Comment 4 David Nolden 2007-01-20 21:56:41 UTC

The backtrace must be different for the current version, because parsing is done in background, and the trace shows a foreground-parse. If it still happens then please send such a backtrace, although the problem might still be the same. It must be something within the lexer..

Comment 5 Craig Magina 2007-03-02 17:19:54 UTC

I've hit this same bug on Kubuntu 6.10.  I crash around 78%.  I'll gather more information later after work.  However I did not get a backtrace.

Comment 6 Amilcar do Carmo Lucas 2007-03-02 17:47:14 UTC

Craig are you using KDevelop 3.4.0 ? Or are you using kdevelop/3.4 SVN branch ?

Comment 7 Craig Magina 2007-03-02 19:11:59 UTC

I'm using using whatever version of kdevelop is in the kubuntu 6.10 repo.  I can get the latest devel version from the svn and see if it dumps there as well.  Currently I am at work and I run FC6, so can't experiment here.

Comment 8 Craig Magina 2007-03-07 03:24:29 UTC

The version I am using is 3.3.4.

Comment 9 Amilcar do Carmo Lucas 2007-03-07 10:53:47 UTC

Then, please update to 3.4.0 from SVN:
http://www.kdevelop.org/index.html?filename=3.4/branches_compiling.html

It fixes more than 500 bugs of the KDevelop 3.3.x release series.
KDevelop 3.3.x development has stopped completely. The Next KDevelop release will be KDevelop 3.4.1.

Comment 10 Craig Magina 2007-03-07 15:01:17 UTC

Thanks.  Checked the Kubuntu page and apparently they put KDE 3.5.6 and Kdevelop 3.4.0 in a new repo.  Still not used to the way the buntu folks set things up.  I ran Gentoo for a couple years before moving to Kubuntu, so used to the way they managed their repos.

Comment 11 Amilcar do Carmo Lucas 2007-03-07 15:13:55 UTC

So, now that you updated, does it still crash ?

Comment 12 Craig Magina 2007-03-07 16:52:14 UTC

Nope, it all works.  Thanks.

Comment 13 Amilcar do Carmo Lucas 2007-03-07 17:09:09 UTC

Fixed in KDevelop 3.4.x

Comment 14 Aleix Pol 2013-03-31 00:46:17 UTC

Moving all the bugs from the CPP Parser. It was not well defined the difference between it and C++ Language Support and people kept reporting in both places indistinctively
