          Issue ID: 20394
           Summary: "one path skips constructor" when exception is thrown
           Product: D
           Version: D2
          Hardware: All
               URL: http://dlang.org/
                OS: All
            Status: NEW
          Severity: normal
          Priority: P3
         Component: dmd
          Assignee: nobody at puremagic.com

struct X
{
        this(int a)
        {
                if(a == 0)
                        this(a, 1);

                else
                        throw new Exception("");
        }

        this(int a, int b) {}
}

The code above fails to compile with "one path skips constructor" error. It can
be worked around by adding "assert(0);" to the else block, but shoudn't
throwing exception be enough?
