Details

openssl's `MemBio::get_buf` has undefined behavior with empty buffers Previously, `MemBio::get_buf` called `slice::from_raw_parts` with a null-pointer, which violates the functions invariants, leading to undefined behavior. In debug builds this would produce an assertion failure. This is now fixed.
