Re: [boost] [math] boost::math::isfinite fails with --fast-math

I'm wandering if this is to be expected, the following code fails if compiled with --fast-math:

//==================================================== #include <boost/math/special_functions/fpclassify.hpp> int main() { const float a = 0.0f/0.0f; assert(not boost::math::isfinite(a)); }

Which fails - does the 0/0 actually yield an infinity? Or is it isfinite that fails? Either way is hard to make guarentees once you enable an option like that. John.
