Looks so. But it is quite unclear what in luaotfload is the problem.
I tried with a dev-luatex and the newest reference fontloader from
context and still get the crash.
Perhaps it is not so much luaotfload doing something wrong but
context adding some code that avoids the problem.
In any case: it is related to kern and the hyphen/font switch. The
following only doesn't crash if one change for font \i +kern to
-kern. Also it seems to be related to otf-fonts, at least I couldn't
find a ttf that breaks -- but this could be by accident.
\input luaotfload.sty
\font \i = {name:texgyreheros:mode=base;+kern;} at 10pt
\font \r = {name:texgyreheros:mode=base;-kern;} at 12pt
\r
aaa-{\i iiii xrmoi}
it's probably not related to the context part as there is a loop in
do_handle_kerning
which is not something in the font loader does but something plugged in
later
(you can probably check it by disabling that call)
