I believe the following is another case of this bug:
https://godbolt.org/z/9r9QdS . MSVC and Clang compile this fine; GCC only
compiles it fine if the `= delete` is not present. It's really weird that GCC
selects the deleted `begin()` even though it does not take an argument.
namespace foo {
namespace detail {
void begin() = delete;
}
inline auto begin = [](auto&& a) {
using detail::begin;
return begin(a);
};
}
#include <array>
int main() {
return *foo::begin(std::array<int, 2>{1, 2});
}
Error message:
<source>: In instantiation of 'foo::<lambda(auto:1&&)> [with auto:1 =
std::array<int, 2>]':
<source>:15:48: required from here
<source>:8:21: error: use of deleted function 'void foo::detail::begin()'
return begin(a);
~~~~~^~~
<source>:3:14: note: declared here
void begin() = delete;
^~~~~
<source>: In function 'int main()':

return *foo::begin(std::array<int, 2>{1, 2});
~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~
