FTBFS with openssl 3.0.1: buffer too small

[Andreas Hasenack]

openssl 3.0.1 fixed a bug[1] which tripped[2] the tests of python-cryptography and made the package fail to build[3]:

lib = <module 'lib'>, ok = False
errors = [<cryptography.hazmat.bindings.openssl.binding._OpenSSLError object at 0x7f5845ec02e0>]

    def _openssl_assert(lib, ok, errors=None):
        if not ok:
            if errors is None:
                errors = _consume_errors(lib)
            errors_with_text = _errors_with_text(errors)

> raise InternalError(
                "Unknown OpenSSL error. This error is commonly encountered when "
                "another library is not cleaning up the OpenSSL error stack. If "
                "you are using cryptography with another library that uses "
                "OpenSSL try disabling it before reporting a bug. Otherwise "
                "please file an issue at https://github.com/pyca/cryptography/"
                "issues with information on how to reproduce "
                "this. ({0!r})".format(errors_with_text),
                errors_with_text,
            )
