Hello,
I used to had an old version of boost (I don't remember exactly which) and my code worked fine. Now I updated to the last version and I started to receive compilation errors in linux when using a std::vector with regular expressions from boost::xpressive, in windows it compiles fine. This code doesn't compile:
#include <vector> #include <boost/xpressive/xpressive.hpp>
typedef boost::xpressive::basic_regex<std::string::const_iterator> regex_t;
int main(int argc, char* argv[]) { std::vector<regex_t> vector; vect.push_back(regex_t());
return 0; }
Compiler output:
<snip>
error: no matching function for call to '_Destroy(const boost::proto::exprns_::expr<boost::proto::tag::address_of, boost::proto::argsns_::list1<boost::xpressive::basic_regex<__gnu_cxx::__normal_iterator<const char*, std::basic_string<char, std::char_traits<char>, std::allocator<char>
&>, 1l>)'
This is arguably a bug in gcc's vector implementation in that it doesn't work property with types that have overloaded unary operator&. It's possible that I might be able to work around the problem in xpressive. Feel free to file a bug against xpressive at svn.boost.org. You should also file a bug against gcc at gcc.gnu.org/bugzilla.
