I'm at a loss to explain this, but this program:
#include <boost/math/special_functions.hpp>
int main() { boost::math::erf(2); }
Compiles cleaning with MSVC-8, but as soon as I add a particular spirit #include:
#include <boost/math/special_functions.hpp> #include <boost/spirit/utility/distinct.hpp>
int main() { boost::math::erf(2); }
Then Boost.Format (used internally be Boost.Math for error message formatting) issues a whole blizzard of warnings, that I actually thought I had fixed.
I'm able to reproduce the behavior you describe and don't have any explanation for it either. But note one thing: the warnings I've got in the second scenario are all C4267 (conversion from size_t to const unsigned int, possible loss of data), which you are not explicitly silencing. If you add the corersponding pragma warning(disable: 4267) at boost/math/policies/error_handling.hpp, compile is clean then in the second scenario as well.
