I thought that was the question that I answered, but I'll try to
rephrase what I wrote:

No.

Strings are <meant> to be swapped out.  If you want to allocate
something permanently, you should use "static" memory allocation:

    m_static();
    pointer_to_thing = ALLOC(type_of_thing, number_of_things);
    m_dynamic();

"thing" should not be a string, an array or a mapping however.
