5557 – [64-Bit] FP (alignment?) issues with Rvalues

import std.stdio;
struct Temp {
 this(float ctorPar) {
 }
 this(double ctorPar) {
 }
 void buggy(float val) const {
 writeln(val);
 }
 void buggy2(double val) const {
 writeln(val);
 }
 void working(real val) const {
 writeln(val);
 }
}
void main() {
 Temp(7.f).buggy(2.); //!<- val == ctorPar
 Temp(7.f).buggy2(0.); //!<- val is some mixup of ctorPar
 Temp(7.f).working(2.);
 Temp(7.).buggy(2.); //!<- val == 0
 Temp(7.).buggy2(2.); //!<- val == ctorPar
 Temp(7.).working(2.);
}
------
Only the functions taking a real gets called with the correct parameter value.
The other two are influenced by the value to the ctor.
