 Thank you for your reply.

 Comments::

 I am not convinced by your point of view.

 1- the compilation step does not deliver any message.

 2- I modify the string by address and this is permitted by C for any entity
not 
    private in its context.

 3- if the compiler gcc allows segmentation fault for basic operations on
pointers,
    I think that this is a severe bug and in consequence the compiler must be
    modified to remedie for such situations.

 This is my point of view.

You're trying to modify a string literal.  That's no-no.

Yeah, I know, but doing the minimization on a 5MLOC program takes time.
