Bug ID: 96716
Summary: GCC reports "object is private" when it's accessed
through proper accessor
Product: gcc
Version: 10.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: vorfeed.canal at gmail dot com
Target Milestone: ---
The following program doesn't work ( https://godbolt.org/z/87cr44 ):
#include <array>
#include <string_view>
class Foo {
public:
auto constexpr getfoo() const -> std::string_view {
return {foo.data(), 2};
}
private:
const std::array<char, 3> foo = {'a', 'b', '\0'};
};
inline constexpr Foo foo;
template <typename>
class Bar {
public:
static constexpr auto bar = foo.getfoo();
};
auto& baz = Bar<int>::bar;
Error message:
<source>: In instantiation of 'constexpr const std::basic_string_view<char>
Bar<int>::bar':
<source>:21:23: required from here
<source>:18:25: error: 'const std::array<char, 3> Foo::foo' is private within
this context
18 | static constexpr auto bar = foo.getfoo();

<source>:10:29: note: declared private here
10 | const std::array<char, 3> foo = {'a', 'b', '\0'};

All other compilers work fine ( https://godbolt.org/z/WvfrPf )
