Хотя лол, логично почему падает.
"Hello, world" изменить нельзя, это константная строка
Every segment has a write protected region where all the constants are stored.
For example:
If I have a const int which is local variable, then it is stored in the write protected region of stack segment.
If I have a global that is initialised const var, then it is stored in the data segment.
If I have an uninitialised const var, then it is stored in the BSS segment...
To summarize, "const" is just a data QUALIFIER, which means that first the compiler has to decide which segment the variable has to be stored and then if the variable is a const, then it qualifies to be stored in the write protected region of that particular segment.
