Bug ID: 98767
Summary: Function signature lost in concept diagnostic message
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: antoshkka at gmail dot com
Target Milestone: ---
Consider the example:
template <typename Function, typename T>
concept Callable1Arg = requires(Function func, T value) {
func(value);
};
// Should fail and fails:
static_assert(Callable1Arg<int(*)(int*), bool>);
The diagnotics has the following line:
"in requirements with 'Function func', 'T value' [with T = bool; Function = int
(*)()]"
However the type of the Function is "int (*)(int*)" not "int (*)()"
