Hello, boost/regex.hpp fails to compile with gcc 4.6, giving the following errors: In file included from /lib/boost/boost/regex/v4/perl_matcher.hpp:578:0, from /lib/boost/boost/regex/v4/regex.hpp:88, from /lib/boost/boost/regex.hpp:31, from test.cpp:1: /lib/boost/boost/regex/v4/perl_matcher_non_recursive.hpp: In member function ‘bool boost::re_detail::perl_matcher<BidiIterator, Allocator, traits>::unwind_short_set_repeat(bool)’: /lib/boost/boost/regex/v4/perl_matcher_non_recursive.hpp:1394:85: error: invalid use of incomplete type ‘const struct boost::regex_traits_wrapper<traits>’ /lib/boost/boost/regex/v4/regex_traits.hpp:163:8: error: declaration of ‘const struct boost::regex_traits_wrapper<traits>’ /lib/boost/boost/regex/v4/perl_matcher_non_recursive.hpp:1394:85: error: invalid type argument of unary ‘*’ (have ‘BidiIterator’) It compiles fine with gcc 4.5. Is this an issue with boost or gcc? Should I report it as a bug? Thanks, Nate.
