lua port

argv[0] = "someActualStringAndNotJustAnUninitializedValue";

So... Problem solved. File under "Too embarrassing".

Lessons learnt: Find axioms ("argv[0] is untouched in lua.c") and their consequences ("I care not about init of argv[0].) Try anti-axiom and consequences. ("...IS..."/"I'll init argv[0]").

Ok I knew this lesson already.

Which makes it double frustrating.
