 The following code

 {{{
 #include <boost/property_tree/ptree.hpp>

 int main (int, char * [])
 {
         boost::property_tree::ptree pt;

         pt.equal_range ("");
 }
 }}}

 generates the following error message using gcc-4.4.3 on 64-bit Snow
 Leopard:

 I see similar error messages using gcc-4.0, 4.2, and 4.3 on Snow[[BR]]
 Leopard, Fedora Core 12, and RHEL 4 with Boost 1.41, 1.42, and trunk from
 SVN.[[BR]]

 Changing the argument to equal_range () to std::string("") or [[BR]]
 boost::property_tree::ptree::key_type ("") generates similar error
 messages.
