           Summary: Crash because of inheritance loop
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel kdevelop org
        ReportedBy: bartoschek gmx de


Version:            (using KDE KDE 3.2.2)

OS:                Linux

Today I made the mistake to write a class which inherits itself. First I did not recognice the problem and tried to call a method of the class. Each time I wrote  instance.  kdevelop crashed, when instance was an object of my class.

I think my class created a cycle in the CodeCompletition Class Store. During the search for all member methods of my class a endless loop was entered and left after stack or heap exhaustion.

Here is how to reproduce the problem:

1. Start a console "Hello World" C++ Project.
2. Add a new file Header.H
3. Insert the following code into the new file:

class Murti : public Murti
{
public:
   static int size();
};

4. Save the file.
5. Go to the main file and type into the main function:

int main() {
Murti a;
a.
}

After you type the dot kdevelop begins to calculate and eventually crashes. 

You can also write  Murti:: and it crashes. I think it does not matter where you write Murti::, it will crash. 


kdevelop should not crash because of such an error. However it would be better if the parser
recognized the error and indicated it to the programmer.
