From 3dabc8c4ccc9b4b0d6dbe8f87353f511d6862bb4 Mon Sep 17 00:00:00 2001 From: Jeff Davis Date: Thu, 13 Aug 2026 20:57:20 -0700 Subject: [PATCH vPG18 1/4] Fixup 5f003855e7 for srclen < 0. No actual problem because no callers used that aspect of the API. Only commit to 18, because that part of the API was removed in commit 6d22c67c3b.
