[harfbuzz 1.3.3] Behdad,
attached you can find a fuzzed font that exhibits very bad behaviour
of `hb_ot_layout_lookup_collect_glyphs': it iterates a few billion
times while looking up data for `mlym', which is certainly invalid
behaviour.
I've run `ftfuzzer' with
valgrind --tool=callgrind ftfuzzer
slow-unit-0030ddf1f5e8ac716938220235fd61b62e7d5848
(which took about 90 minutes on my not so old Notebook); attached is
its output too so that you can view it with `kcachegrind' or something
similar without running it by yourself.
Please fix :-)
Werner
