Bug ID: 103783
Summary: Ambiguous overload between constrained static member
and unconstrained non-static member
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: barry.revzin at gmail dot com
Target Milestone: ---
>From StackOverflow (https://stackoverflow.com/q/70429541/2069064):
template<bool b>
struct s {
void f() const;
static void f() requires b;
};
void g() {
s<true>().f();
}
gcc rejects with:
<source>: In function 'void g()':
<source>:8:20: error: call of overloaded 'f()' is ambiguous
8 | s<true>().f();
| ~~~~~~~~~~~^~
<source>:3:14: note: candidate: 'void s<b>::f() const [with bool b = true]'
3 | void f() const;
| ^
<source>:4:21: note: candidate: 'static void s<b>::f() requires b [with bool b
= true]'
4 | static void f() requires b;
| ^
I don't think this is an instance of P2113 with non-equivalent templates, seems
like this case should compile. clang and msvc accept.
