  // Issue 4396. Arrays of bytes are not required to be
  // word aligned. 5g should use MOVB to load the address
  // of s.g[0] for its nil check.
  //
  // This test _may_ fail on arm, but requires the host to 
  // trap unaligned loads. This is generally done with
  //
  // echo "4" > /proc/cpu/alignment
