           Summary: SIGSEGV clicking at the end of a method call
           Product: kdevelop
           Version: 3.4.1
          Platform: Debian stable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-bugs kdevelop org
        ReportedBy: woefel woefel de

Version:           3.4.1 (using KDE KDE 3.5.5)
Installed from:    Debian stable Packages
Compiler:          gcc 404 
OS:                Linux

kdevelop crashes reproducibly when clicking between the last parameter and th closing \
bracket of a specific class method call. It does not crash at other methods or other \
positions (e.g. at other parameters).

The output of valgrind is:
kdevelop (cpp support): CppCodeCompletion::evaluateExpressionAt( 627, 265 )
kdevelop (cpp support): evaluating line "if(currentPlate==2) { \
computeFemCond(subdivision, orientation, fsize, visf, visfolder, compatibilityMode, \
