Bug 6391 – Line-less error when passing the '.im' of floating pointer value by reference

Test case: ---------------- void s6391(ref double x){} void bug6391() { double d = 1; s6391(d.im); } ---------------- x.d(4): Error: function x.s6391 (ref double x) is not callable using argument types (double) Error: 0 is not an lvalue ---------------- With template methods, it becomes hard to trace back where is the cause of this line-less error, e.g. ------------------------ void t6391(R)(ref R x){ if (x.re > 0) t6391(x.im); } void bug6391b() { double d = 1; t6391(d); } ------------------------ Error: 0 is not an lvalue // where? x.d(7): Error: template instance x.t6391!(double) error instantiating // why? ------------------------
