Hi Steve,
>I ask this question last week, is this not the right list for this question?
This is the right list for your question.
This list is a user-community volunteer list. Questions are posed by anyone, worldwide, and answers are provided by anyone, worldwide.
Those who regularly answer questions are, what I'd call, self-nominated "experts" on GCC. There's only a few that are part of FSF or GCC developers per se.
So if you ask a question that no one on the "panel of experts" can answer, you end up with (in radio terms) dead air.
I know that this doesn't answer your initial question, but it does explain why no one volunteered an answer.
I, for one, do not know the answer to your initial question. I'm more of a "C++ language lawyer" than a "nitty gritty internals of GCC guru".
