Luatex is trying to hyphenate a word without any current language
(lang = 0x3 in the stacktrace, it should be a pointer to a structure).

the language structure is (re)initialized from a partial bitfield,
and it is possible that either endianness or byte (word) sizes are
biting there. What I do not understand is why it happens while on
page 81 (I would expect a problem like that to hit immediately).

Are you doing anything special on that page?

Best wishes,
