--- Comment #2 from Guillaume Racicot <gufideg at gmail dot com> ---
Seems this bug also apply to deduced return type:
template <typename T>
void foo();
void bar() {
int i;
auto l = [&i]() -> decltype(auto) {
foo<decltype(i)>();
return i;
};
l();
foo<decltype(l())>();
}
Yield the assembly:
bar():
sub rsp, 8
call void foo<int>()
add rsp, 8
jmp void foo<int&>()
Strangely, replacing the return expression to `return
static_cast<decltype(i)>(i);` seems to fix the behaviour.
