[boost] lexical_cast problem

I've just updated my project to use boost 1.30 and also gcc 3.2 and see 
exception which reads:

   bad lexical cast: source type value could not be interpreted as target,  
   Target=i, Source=Ss

The simple reproduction recipe is: 

    #include <boost/lexical_cast.hpp>
    #include <string>

   int main()
   {
       boost::lexical_cast<int>(std::string(" 0"));
   }

Note the space in string. The exception does not occur with gcc 2.95, but only 
with 3.2. I wonder if this should/can be fixed? Personally, I'd expect this 
code to work.

And a related note: the exception's what() above is not quite helpfull. Is it 
possible to output the stringstream content (if source -> stringstream 
conversion was successfull?)
