7532	lexical_cast fails on complex number with spaces	J. J. Ramsey <jjramsey@…>	Antony Polukhin	"Here's the test code that shows the problem:

{{{
#include <boost/lexical_cast.hpp>
#include <iostream>
#include <sstream>
#include <string>

typedef std::complex<double> Complex;

int main()
{
  std::string goodComplex(""(1,2)""), badComplex(""(1, 2)"");

  try {
    Complex foo = boost::lexical_cast<Complex>(goodComplex);
    std::cout << ""goodComplex = "" << foo << ""\n"";
  }
  catch (boost::bad_lexical_cast const & e) {
    std::cerr << ""goodComplex failed: "" << e.what() << ""\n"";
  }
  
  try {
    Complex foo = boost::lexical_cast<Complex>(badComplex);
    std::cout << ""badComplex = "" << foo << ""\n"";
  }
  catch (boost::bad_lexical_cast const & e) {
    std::cerr  << ""badComplex failed: ""<< e.what() << ""\n"";
  }
  
  {
    /* Using a stringstream works, though. */
    Complex foo;
    std::istringstream tmpStream(badComplex);
    tmpStream >> foo;
    std::cout << ""badComplex printed with stringstream = "" << foo << ""\n"";
  }

}
}}}

On my machine, with g++ 4.1.2, I get the following result:

{{{
goodComplex = (1,2)
badComplex failed: bad lexical cast: source type value could not be interpreted as target
badComplex printed with stringstream = (1,2)
}}}

For some reason, lexical_cast chokes on the space after the comma, but the stringstream has no problem. "	Bugs	closed	To Be Determined	lexical_cast	Boost 1.50.0	Problem	wontfix
