  "message": "Harden `PYBIND11_MODULE_PYINIT` and `get_internals()` against crashes during module init (#6018)\n\n* Wrap ensure_internals() in try-catch in PYBIND11_MODULE_PYINIT\n\nPreviously, ensure_internals() was called without exception handling\nin the PyInit_* function (PYBIND11_MODULE_PYINIT), while the same call\nin PYBIND11_MODULE_EXEC was already wrapped in try-catch. On MSVC,\na C++ exception propagating through the extern \"C\" PyInit_* boundary\nis undefined behavior, which can manifest as an access violation\ninstead of a clean error message. This is a potential contributor to\ncrashes like gh-5993. Wrap the entire PyInit body in try/catch using\nthe existing PYBIND11_CATCH_INIT_EXCEPTIONS pattern.\n\nMade-with: Cursor\n\n* Add nullptr guards in get_internals() for better crash diagnostics\n\nAdd explicit null checks after get_pp() and create_pp_content_once()\nin get_internals(), calling pybind11_fail() with descriptive messages.\nThese guards convert potential null-pointer dereferences (which produce\nunhelpful access-violation crashes, especially on Windows) into clear\nruntime_error messages that can be caught and reported as ImportError\nby the try-catch added in the previous commit.\n\nMade-with: Cursor",
