            Bug ID: 101719
           Summary: "Already defined" error in case of function
                    specialization with concept
           Product: gcc
           Version: 11.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fchelnokov at gmail dot com
  Target Milestone: ---

The following correct code:
```
#include <iostream>

constexpr int p(auto) { return 0; }
constexpr int q() { return p(0); }
constexpr int p(auto) requires true { return 1; }

static_assert(p(0) == 1);
static_assert(q() == 0);

int main()
{
    std::cout << q() << p(0) << '\n';
}
```
produces the error
```
Error: symbol `_Z1pIiEiT_' is already defined
```
