/*
   This simple test program is supposed to output 4
   It was seen that compiling with optimization it works,
   but without optimization it fails.
   So this must be retested with all levels of optimization, i.e.
   * qvc test.c
   * qvc test.c -O
   * qvc test.c -O0
   * qvc test.c -O1
   * qvc test.c -O2
   * qvc test.c -O3
