           Summary: Crash while moving inside a cpp file with the cursor
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel kdevelop org
        ReportedBy: david familie-ecker net


Version:           3.0.90-CVS (using KDE KDE 3.2.2)
Installed from:    Compiled From Sources
Compiler:          gcc-3.3.3 glibc 2.3 - linux kernel 2.6.5
OS:                Linux

while moving up with the cursors buttons on the keyboard in a c++ file
kdevelop crashed with SIGSERV(11).
The german message at the top of the trace says that the stack frame can't be
read because either kdevelop is compiled without support for backtracing or
the stack frame is unusable because of the crash.

KDevelop was running for 3 days without being shutdown.

Eine korrekte Rückverfolgung ist nicht möglich.
Wahrscheinlich sind die Dateien Ihres Systems in einer Weise erstellt worden,
die eine solche Rückverfolgung (Backtrace) nicht erlaubt. Oder der so
genannte "Stack Frame" für das Programm wurde durch den Absturz unbrauchbar
gemacht.

Using host libthread_db library "/lib/libthread_db.so.1".
