           Summary: Crash when parsing a piece of code
           Product: kdevelop
           Version: git master
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-bugs@kdevelop.org
        ReportedBy: edub4rt@gmail.com


Version:           git master
OS:                Linux

The following line taken from the C++0x wikipedia page makes kdevelop from git
master instantly crash:

NonCopyable(const NonCopyable&) = delete;

Just paste it anywhere, the struct doesn't ever need to be declared.
