[Bug c++/37276] New: Trouble with some (C99?) math builtins and namespace std

["paolo dot carlini at oracle dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Hi, I'm getting this annoying run-time Seg-fault for the below. Apparently,
isn't a regression, but really, if we could fix it, the C++ library would
benefit a lot from the fix!

////////////////

namespace my_std
{
  inline double
  atan(double __x)
  { return __builtin_atan(__x); }

  inline double
  atanh(double __x)
  { return __builtin_atanh(__x); }
}

namespace std
{
  inline double
  atan(double __x)
  { return __builtin_atan(__x); }

  inline double
  atanh(double __x)
  { return __builtin_atanh(__x); }
}

int main()
{
  double d;

  my_std::atan(.3);  // works
  my_std::atanh(.3); // works

  std::atan(.3);     // works
  std::atanh(.3);    // seg-faults at run-time
}
