1. [VM] Fix potential undefined behavior …

   Use pointer arithmetic instead of direct array access to avoid
   compilers, specifically GCC, to discover undefined behavior and
   generate unintended code when optimization is turned on.
   
   The array involved is `pSeries->val_serie`, which is declared as
   a fixed sized array of size 1. However, `index` is always a
   non-negative integer, and we want to access the memory at
   `-index`, which is either zero or negative.
