It fails on x86 using x87 floating point, with the inliner not run,
because of 1505, yes. Gonsolo, is that your situation?

Hi!
<tangens_bug.cc>
#include <iostream>
#include <cmath>
int main()
{
float a = 0.3;
double b = 0.3;
float result_a = std::tan( a );
float result_b = std::tan( b );
std::cout << "tan float: " << result_a << std::endl;
std::cout << "tan double: " << result_b << std::endl;
}
