If you're using gcc 4.8.2 to compile ... anything, really ... but certainly
Plan 9 or Inferno components,
and those use for loops with arrays, be sure to include the compilation
options
-fno-strict-aliasing\
-fno-aggressive-loop-optimizations\
and it will save you some time and effort.
It will save compilation time (not that you'll notice with that sluggard)
because it won't
fuss even more with your program, and it will save effort, because you
won't have
to debug simple loops that have bounds changed, are removed completely, or
otherwise wrecked.
You can find discussions of it elsewhere (which is how I found compiler
options to stop it).
I'd forgotten all about it until it surfaced again.
