New subject: It seems a bug in boost::property_tree when I use custom allocator.

29 Dec 2010


      I use custom stl allocator to replace std::basic_string like this:
 
   typedef std::basic_string MyString;
 
    I want basic_ptree can use my allocator to do parse work, so I write code like this:
   typedef boost::property_tree::basic_ptree PropertyTree;
    PropertyTree propertyTree;
    boost::property_tree::read_ini(std::ifstream(configFile.c_str()), propertyTree);
 
   And I met error at ini_parser.hpp, line 109~111:
   Str key = property_tree::detail::trim(
    line.substr(1, end - 1), stream.getloc());
    if (local.find(key) != local.not_found())
 
    the Str is a typedef at the begin of this function:
    typedef std::basic_string<Ch> Str;
 
    So my custom string can not assign to the key, so it seems can not use custom allocator at all. There have the same problem in xml_parser.

It seems a bug in boost::property_tree when I use custom allocator.
