tests/hazmat/primitives/test_pkcs7.py::TestPKCS7SignatureBuilder::test_sign_byteslike crashes: unsafe precondition(s) violated: slice::from_raw_parts requires the pointer to be aligned and non-null, and the total size of the slice not to exceed isize::MAX #11319
Description
Reproduced with Python 3.12.4 (but also PyPy3.10 7.3.16 and Python 3.10.14), on top of 0e175c7 and 43.0.0 release, on Gentoo Linux amd64. rustc 1.79.0 (129f3b996 2024-06-10) (gentoo)
To reproduce:
pip install -v -e '.[test]' -Cbuild-args=--profile=dev
export RUST_BACKTRACE=1
python -m pytest -vv -s tests/hazmat/primitives/test_pkcs7.py::TestPKCS7SignatureBuilder::test_sign_byteslike
