It seems that the 'pow' function is broken. Note that here,

   2.8147497671066e+014  == 2.8147497671065e+014 also false (line 55)

the results differ in the last bit. (The second number is the result
of an exponentiation. The first result should be the expected value.)

Probably that first 'a' is not actually 625, too. May you change that
first test (coroutine.lua) to print 'a - 625' (or else to print 'a' with
format "%a")? Or better yet, check the pow function with some simple
tests?

  print(2^3 - 8)
  print(3^4 - 81)
  ...)
