+Subject: [PATCH 4/6] Fix #74267: segfault with streams and invalid data
+
+If the current character is a line break character, it cannot be a tab
+or space character, so we would always fail with an invalid sequence
+error.  Obviously, these `scan_stat == 4` conditions are meant to be
+exclusive.
+
+Furthermore, if `in_pp == NULL || in_left_p == NULL` is true, we hit a
+segfault if we are not returning right away.  Obviously, the additional
+constraints don't make sense, so we remove them.
+
