Bug ID: 47217
Summary: Error propagating the tru type of an expression:
"non-literal type 'auto' cannot be used in a constant
expression"
Product: clang
Version: 10.0
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++17
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected],

The following code
template <typename... B>
struct Sample {
template <typename A>
static constexpr auto bar = 0;
};
constexpr auto fail = Sample<>::template bar<int>;
Fails to compile with this error: "non-literal type 'auto' cannot be used in a
constant expression"
Looks like a bug to me (and this only happens in clang).
