<pre>Both clang and gcc agree that the following should not compile
struct foo {
void func();
};
void zed(const foo& v) {
[v]() mutable {
v.func();
}();
}
The problem being that the member corresponding to v is now const.
But the following function compiles with clang while gcc rejects it
void bar(foo& v) {
[v]() {
[v]() mutable {
v.func();
}();
}();
}
The operator() of the outer lambda should be const, so the v in the inner
lambda should be const too, and gcc is correct in rejecting this as far as I
can tell.</pre>
