Re: [Boost-users] xpressive compilation error

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

typedef boost::xpressive::basic_regexstd::string::const_iterator regex_t;

int main(int argc, char* argv[]) { std::vector vector; vect.push_back(regex_t());

return 0; }

Compiler output:

<snip>

error: no matching function for call to '_Destroy(const boost::proto::exprns_::expr

&>, 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.
