From 37a7f1b0997466bb088df82f5fe35fe6d1cebb22 Mon Sep 17 00:00:00 2001 From: "Miss Islington (bot)" <31488909+miss-islington@users.noreply.github.com> Date: Wed, 25 May 2022 10:50:24 -0700 Subject: [PATCH] [3.11] gh-93035: [Enum] Fix IntFlag crash when no single-bit members (GH-93076) (GH-93197) `EnumType` attempts to create a custom docstring for each enum/flag, but that was failing with pathological flags that had no members (only multi-bit aliases).
