So, fix the question.

If the question is "why do I get a segfault?" and we find out he's trying to write C code to title-case a string in-place, and he's passed in a string literal, we can edit the question to "Why do I get a segfault trying to modify a string literal?" or similar.

If the objection is that answering the real question will confuse people, then make the question match the correct answer.
