This I don't understand anymore. The code in question is:

    some_spirit_grammar g;
    boost::spirit::pt_parse(it, end, g);

the programm crashes inside pt_parse because of g == 0xcccccccc (destroyed
object), where pt_parse takes 'g' by const reference. Initially 'g' was
defined as a function local static instance, which I've removed now because
I had the suspicion CW8.x couldn't handle that correctly.

Any clues?
