--- Comment #4 from Matt Godbolt <matt at godbolt dot org> ---
Agreed re: cast/FE.
I couldn't quite get your example to fail as the "o" parameter is unusued
(which would be a good clue!
#include <utility> // for std::move
struct B {
int a; int b;
B(B &&o)
: a(b),
b(o.a) {}
};
passes just fine though; which is grist for the mill for bug 19808 being fixed
(e.g. https://godbolt.org/g/QHLCQv )
Thanks again!
