Since there's apparently no way to edit a comment, the previous comment
should read:

I thought we agreed a long time ago not to check for either overflows or
underflows when ZORBA_WITH_BIG_INTEGER=OFF.

Title:
  negative result for fib(95)

Status in Zorba - The XQuery Processor:
  New

Bug description:
  declare function local:fib($n as xs:integer) as xs:integer
  {
   if ($n eq 0) then 0
   else if ($n eq 1) then 1
   else local:fib($n - 1) + local:fib($n - 2)
  };

  local:fib(95)

  gives  -4953053512429003327 but should return 31940434634990099905.
  This seems to be a overflow in numerics. fib(90) gives the correct
  result.
