I think so, too. On my environment, it->object (and it->string) is a
Lisp string " 164". The value of it->current.pos.charpos is 4139
rather than OP's 4138. Perhaps the text is slightly different.

I noticed that if I turn off prettify-symbol-mode, then it does not
crash. Attached are the screenshots with and without
prettify-symbol-mode: the former crashes and the latter does not. The
original contents of Line 164 is
forall T1, 1 <= size_typ T1.
and the strings "forall" and "<=" are composed by the following
prettify-symbols-alist value:
(("|-" . 8866)
("||" . 8214)
("/\\" . 8743)
("\\/" . 8744)
("->" . 8594)
("<-" . 8592)
("<->" . 8596)
("=>" . 8658)
("<=" . 8804)
(">=" . 8805)
("<>" . 8800)
("True" . 8868)
("False" . 8869)
("fun" . 955)
("forall" . 8704)
("exists" . 8707)
("nat" . 8469)
("Prop" . 8473)
("Real" . 8477)
("bool" . 120121)
(">->" . 8611)
("-->" . 10230)
("<--" . 10229)
("<-->" . 10231)
("==>" . 10233)
("<==" . 10232)
("~~>" . 10239)
("<~~" . 11059))
