Indexing across array boundaries is not allowed by C99.
Signed-off-by: Mans Rullgard <mans@mansr.com>

Subtracting a (positive) value from the address of an array violates
C99 section 6.5.6:

  If both the pointer operand and the result point to elements of the
  same array object, or one past the last element of the array object,
  the evaluation shall not produce an overflow; otherwise, the
  behavior is undefined.
