GCC 4.6.0 rejects the *Boost* intrusive header list.hpp. Here's the command line: g++ -std=c++0x -O2 -s -W -Wall -I /home/brian/boost_1_46_1 -c -o jaj.o jaj.cc and the output: In file included from jaj.cc:1:0: /home/brian/boost_1_46_1/*boost*/intrusive/list.hpp: In static member function =91static *boost*::intrusive::list_impl<Config>& *boost*::intrusive::list_impl<Config>::priv_container_from_end_iterator(const const_iterator&)=92: /home/brian/boost_1_46_1/*boost*/intrusive/list.hpp:1291:89: sorry, unimplemented: unexpected ast of kind field_decl /home/brian/boost_1_46_1/*boost*/intrusive/list.hpp:1291: confused by earlier errors, bailing out Preprocessed source stored into /tmp/ccRWz6ZT.out file, please attach this to your bugreport. The .cc file is one line -- an include of list.hpp. Here's the function that it is complaining about: private: static list_impl &priv_container_from_end_iterator(const const_iterator &end_iterator) { root_plus_size *r = detail::parent_from_member ( detail::boost_intrusive_get_pointer(end_iterator.pointed_node()), &root_plus_size::root_); data_t *d = detail::parent_from_member ( r, &data_t::root_plus_size_); list_impl *s = detail::parent_from_member(d, &list_impl::data_); return *s; } 1291 is the line that starts with "list_impl *s = " I'd like to be able to begin using GCC 4.6, but this is preventing me from doing so. Would someone with GCC 4.7 or 4.6.1 test this and report the results?
