            Bug ID: 200
           Summary: Excess precision appears to be precisely defined in D
           Product: GDC
           Version: development
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: gdc
          Assignee: ibuclaw@gdcproject.org
          Reporter: ibuclaw@gdcproject.org

Though it's not documented anywhere (as far as I can see), we should not be tripping over GCC bug 323, and yet we have this problem with the optimizer.

import core.stdc.stdio;

void test(double x, double y)
{
  const double y2 = x + 1.0;
  assert(y == y2);
}

void main()
{
  const double x = .012;
  const double y = x + 1.0;
  test(x, y);
}
