Subject: Fix assertion violation in pdumper.c
X-Git-Tag: emacs-28.0.90~6576

Fix assertion violation in pdumper.c

* src/pdumper.c (pdumper_find_object_type_impl): When checking
last_mark_bits, require the offset to be less than
discardable_start, not cold_start.  This fixes a typo introduced in
2020-08-14T21:33:21Z!eggert@cs.ucla.edu (Bug#42832).
