símbolo indefinido: _PyThreadState_Current al usar código C++ envuelto con pybind

Cuando ejecuto bazel test ..., el código en cpp se compila, pero Python se bloquea.
Leí esto antes de escribir esta pregunta, pero no puedo encontrar ninguna solución:

Python: Python 3.8.10

g++: g++ (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

pybind11: v2.8.1

Código C++:

//math.cc

#include <pybind11 pybind11.h="">

int add(int i, int j) {
  return i + j;
}

int subtract(int i, int j) {
  return i - j;
}

namespace py = pybind11;

PYBIND11_MODULE(math, m) {
  m.def("add", &add);

  m.def("subtract", &subtract);
}

Código Python:

# math_test.py

from module import t_math

assert t_math.add(1, 1) == 2
assert t_math.subtract(1, 1) == 0

BUILD:

load("@pybind11_bazel//:build_defs.bzl", "pybind_extension")

  name = "t_math",
  srcs = ["math.cc"],

  size = "small",
  srcs = ["math_test.py"],
  data = [":t_math.so"],
)
