           Summary: Crash when editing C++ files
           Product: kdevelop
           Version: CVS
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: logic at jrlogic.dyndns.org


Version:           CVS (using KDE KDE 3.1.4)
Installed from:    Gentoo Packages
Compiler:          gcc-3.2.3 
OS:          Linux

KDevelop sometimes crashes when editing C++ code. This crash happened while editing a new header file. I am running on a dual athlon-mp system.

I've also experienced more frequent crashes on a dual pentium III system. Those crashes happened in the Kate KPart, and may be unrelated (the backtrace is different, and I was blaming an out-dated KDE 3.1.3 installation), though they are always when editing large C++ files.

This is the first time KDevelop has crashed on my dual athlon system.
