Re: [Boost-users] boost::trim throwing std::bad_cast exeption with custom basic_string

I have a custom basic_string as follows:

typedef basic_string<unsigned int> ustring;

so if I pass an instance of ustring to boost:trim it throws an std::bad_cast exception.

ustring str; boost::trim(str);

It doesn't raise exceptions on MSVC10, so I guess the problem is in the standard library implementation you use.
