wanted : simple debugging task
 

I am learning Cpp and have already written a few simple e.g. program which finds prime numbers *with* error handling (e.g. user wanting "u" prime numbers) and i was wondering if there was a simple but buggy program that needs de-buging ?

Because i have learnt most of cpp from reading source.

and it would be both a good learning experience and good for the GNU community

I didn't understand what exactly you want, Do you want a program and want to debug it so that you can learn debugging, or waht??

well yes..... cpp programs that make prime numbers are really quite useless arent they ?
So a "real world" program would be good.

And i dont have any program that i need and could write my self.
