P.S.: s/section/segment/ Someone else would have to answer that question. I assume anything that is kind of static, like globals, class variables, D's .init blocks. It makes sense to me, because the compiler can issue static references to that data, instead of generating code that creates space for it e.g. on the heap and have the program use a pointer to get at it. -- Marco
