Bug report -- Python Exception <class 'RecursionError'>: maximum recursion depth exceeded

[TechHara <techhara@outlook.com>]

Hello,

I am reporting a bug that I found. The following script reproduces the
bug on Ubuntu x64 running g++ (Ubuntu 11.3.0-1ubuntu1~22.04) 11.3.0 and
GNU gdb (Ubuntu 12.1-0ubuntu1~22.04) 12.1.

```
cat << EOF > main.cc
#include <iostream>
#include <memory>

int main() {
    auto ptr = std::make_shared<int>(0);
    std::cout << ptr.use_count() << "\n";
    return 0;
}
EOF

g++ -std=c++17 -g main.cc
./a.out
gdb -q a.out -ex "set confirm off" -ex "b 7" -ex "r" -ex "p
ptr.use_count()" -ex "q"
```

The output of the script is
```
(gdb) p ptr.use_count()
Python Exception <class 'RecursionError'>: maximum recursion depth
exceeded
Error while looking for matching xmethod workers defined in Python.
```

With python print-stack full enabled, I get
```
(gdb) set python print-stack full
(gdb) p ptr.use_count()
Traceback (most recent call last):

RecursionError: maximum recursion depth exceeded

```

If I were to compile with clang and run the same commands with GDB,
1) -stdlib=libstdc++ ==> same error
2) -stdlib=libc++ ==> works fine

LLDB, on the other hand, works fine on all scenarios I tested.

Thanks.
