--- Comment #2 from BENAÏSSA <ka_bena at yahoo dot fr> --- 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.
