[spirit2] segfault upon grammar instantiation

[vallentin@…]

I recently switched from g++ 4.0 to g++ 4.2 and now get this warning. I am using the 1.37 beta.

***/boost-1_37/boost/spirit/home/support/nonterminal/detail/nonterminal_fcall.hpp:53: warning: missing braces around initializer for 'boost::spirit::parameterized_nonterminal<boost::spirit::qi::rule<__gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > >, void ()(std::basic_string<char, std::char_traits<char>, std::allocator<char> >), vast::bro::bro_white_space<__gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char> > > >, boost::fusion::unused_type>, boost::fusion::vector<boost::phoenix::actor<boost::spirit::local_var<0> >, boost::fusion::void_, boost::fusion::void_, boost::fusion::void_, boost::fusion::void_, boost::fusion::void_, boost::fusion::void_, boost::fusion::void_, boost::fusion::void_, boost::fusion::void_> >'

Later on, my application segfaults. Here is the stack trace:

Let me know if you need more context from my application, I am not sure where to start from here.

Is this still a problem? If yes, could you please provide a minimal example reproducing this problem? Otherwise it's not possible to fix it.

[Joel de Guzman]

Yes, please post a minimal example reproducing this. There's no other way for me to tell.

[vallentin@…]

Replying to djowel:

Yes, please post a minimal example reproducing this. There's no other way for me to tell.

It's actually solved, I am using gcc 4.3 for a while now and the problem doesn't exist anymore.
