[boost] Re: [wave] cw-8.3 segfault..

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? Regards Hartmut

Are you running into the CW 8.3 "CRTP bug" where casting to a derived class reference can induce a copy? -- Dave Abrahams Boost Consulting www.boost-consulting.com
