+Subject: [PATCH] _GSConverter: handle stray 'GS' in output gracefully
+
+Search the GS output stream for either "GS<" or "GS>" explicitly rather
+than any "GS", in order to prevent the code from wrongly matching stray
+"GS".  This fixes a recent test regression on Gentoo where the following
+output seems to have been wrongly matched:
+
+    **** Error 'gs' ignored -- ExtGState missing from Resources.
+                                  ^^
+
+Fixes #20472
