No its not a bug anyway. Your statment
        void (*f)() = x;
     does two things 1. declares a function pinter and then assing it the
     value of x.
     As x is not a funcition point rather an char pointer so it is type
     promoted. And this method has some uses in pc enviornment i think it
     can have some uses in the PIC enviorment too. as in the PIC your
     strings are stored in the code area.

     anyway its not a bug.

As far as I can see, this is a C bug or a programmer bug.

Of course, a PIC programmer wouldn't think of this, since it is impossible to
execute data on a PIC.
