Stacktraces of lua sorting:

a = {}
for i=1,50000 do
  a[i] = math.random()
end

table.sort(a, function(x,y) return y<x end)

I think I got to the bottom of this. They key is that this only happens when serialised compilation is turned off. What happens is that we try to compile a (longish) trace just before the end of the program. While one thread is busy compiling the trace, the lua program suddenly terminates. Presumably the cleanup happening when lua exits, destroys stuff the compiler depends on.

You can verify this by adding prints to certain parts of yk and lua. Or alternatively, using this modified program, which runs just fine:

function sleep(n)
  os.execute("sleep " .. tonumber(n))
end

a = {}
for i=1,50000 do
  a[i] = math.random()
end
 
table.sort(a, function(x,y) return y<x end)

sleep(2)

This seems related to the general "the current JIT has bugs" things that will (one way or another) be bypassed, so closing.
