Please Yichun, this is uncalled for. Those bugs were truly obscure
and rare. It's absolutely not helpful to suggest that *any* kind
of random observation without context is a) truly a bug in LuaJIT
and b) related in any way to those recently fixed. I mean ... most
of these obscure issues were already present in 2.0, but nobody
else has reported them for several years.
Also, swamping a newcomer with rather advanced advice about
debugging the internals of LuaJIT itself is unlikely to be
effective.
Occam's razor tells us there has to be a much simpler reason for a
very basic 6-liner to malfunction. Especially given that it
doesn't reproduce for anyone else. And any speculation is pointless
without context, which the original reporter failed to provide.
