--- Comment #4 from Walter Bright <bugzilla at digitalmars.com> ---
The test case:

  real foo();

  void test1() {
    cast(void)foo();
  }

  void test2() {
    foo();
  }

compiles to:

  __D4test5test1FZv:
             call    __D4test3fooFZe
             ret

  __D4test5test2FZv:
             call    __D4test3fooFZe
             fstp    ST
             ret

which nicely illustrates the problem.
