           Summary: kdevelop crashes on closing some cpp files while using
                    kyzis embedded editor
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-bugs kdevelop org
        ReportedBy: marchand kde org


Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 3.4.2 / gcc 3.3.3 
OS:                Linux

We (kyzis developers) investigate a lot in this bug and believe the problem reside in \
kdevelop's cppparser. you can checkout more infos from our bug tracking at \
http://bugs.yzis.org/show_bug.cgi?id=44.

steps to reproduce :
import yzis trunk into kdevelop (having the project loaded is necessary, I think the \
cppparser is not used otherwise), then open libyzis/syntaxhighlight.cpp, then close \
it. kdevelop then crashes, the bt shows kdevelop trying to access a freed QString \
apparently.

valgrind's output of kdevelop can be found at http://www.yzis.org/~mikmak/crash

I would be pleased that anyone being knowledgeable with the cppparser can give this a \
look since I was not able to fix it myself. This bug only occurs with kdevelop, \
quanta for example runs fine, kyzis alone runs fine (valgrind is happy with it too). \
The bug seems to happen after kyzis is closed (kyzis using swapfiles, the swapfile is \
correctly deleted so I believe kyzis is closed correctly before the crash).

so any help/suggestion is welcome ...

Cheers,
Mik
