Sorry, but it is not safe: sure, the pointer still 'points' at the same address but the contents of the strings are not protected anymore

So, later in your program you may find garbage characters in your string and you don't know way. It is like using a string allocated with new after having deleted it.

char* f()
{
	char buffer[20] = {0};
	strcpy(buffer, "Hello");
	return buffer;
}
