The bug has nothing to do with _ENV. The following trivial program
segfaults:

-----------------------------
local a
function t()
  local mod = 1
  a, mod = 1
end

t()
-----------------------------

The parser generates a wrong opcode (refering to 'a' as upvalue 1 instead
of 0), but I did not have time yet to find why.
