Side effect between exit & .HLL

[François PERRAD]

With the following code :
  .sub main
      print "reached\n"
      exit 1
      print "not reached\n"
  .end
I obtain :
        reached

But after adding a .HLL directive
  .HLL 'Lua', 'lua_group'

  .sub main
      print "reached\n"
      exit 1
      print "not reached\n"
  .end

I obtain :
        reached
        No exception handler and no message
        current instr.: 'main' pc 2 (exit.pir:5)

Is it a feature or not ?

François.
