Ammar Askar <am...@ammaraskar.com> added the comment: Opened https://github.com/python/cpython/pull/17064 to fix this. Essentially it's a tiny little oversight in the back-porting. In the 3.7 branch, we perform an attribute lookup for `from_param` before the union checking code, so we must remember to DECREF it. This is unlike master where the attribute lookup happens after the union checking code.
