From aedaa405953f6fad29ecd5e16d10de126ecb1af2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Dani=C3=ABl=20van=20de=20Giessen?= Date: Wed, 16 Apr 2025 14:17:14 +0200 Subject: [PATCH] py/modthread: Initialize thread state nlr_top to NULL. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This ensures the check in MP_NLR_JUMP_HEAD works as expected and nlr_jump_fail gets called so we get a bit better error message.
