 Hello,

 the following code produces the error with MS Visual Studio 2005:

 double f = std::numeric_limits<double>::infinity();
 std::string str = boost::str(boost::format("%0.5f") % f);

 will result in a VERY LONG string:
 1000000000000 ... 000.#INF0

 The format specifiers %e, %g and %1% work correctly, however.
 The problem arises with version 1.33 and 1.36 of the Boost library.

 Thank you in advance for your assistance.
