dmajor added a comment.
Before the revert, our bots hit the following issue where we only error out
when `-Wall` is given, so there's definitely something strange going on. Also
happens with @Quuxplusone's suggested change applied.
$ cat test.cpp
template < class > class RefPtr {
public:
~RefPtr();
template < typename d > RefPtr(d);
operator int() &;
operator int() && = delete;
};
class X;
bool e() {
RefPtr< X > frame(0);
return frame;
}
$ clang -cc1 -std=c++17 test.cpp
$ clang -cc1 -std=c++17 test.cpp -Wall
test.cpp:11:10: error: conversion function from 'RefPtr<X>' to 'bool' invokes
a deleted function
return frame;
^~~~~
test.cpp:6:3: note: 'operator int' has been explicitly marked deleted here
operator int() && = delete;
^
