Minimal testcase
$ g++-snapshot --version
g++-snapshot (Debian 20130509-1) 4.9.0 20130509 (experimental) [trunk revision
198734]
$ cat main.cpp
struct foo {
void bar() & {}
void bar() && {}
};
int main()
{
// No complaints
auto p = &foo::bar;
// error: pointer-to-member-function type 'void (foo::*)() &' requires an
lvalue
(foo{}.*p)();
}
$ g++-snapshot -std=c++11 main.cpp
main.cpp: In function 'int main()':
main.cpp:11:13: error: pointer-to-member-function type 'void (foo::*)() &'
requires an lvalue
(foo{}.*p)();
^
I would have thought &foo::bar would have been ambiguous outside of any
context.
