I suggested keeping a non-volatile pointer (to the alloc'd memory) and
a volatile pointer to the same memory, and using whichever was
appropriate.  I still think that's a good idea.  The warning from gcc
*is* correct: you're casting away volatile.  Sure, you might be able
to find a way to shut up the warning, but is it not surely better to
fix the code instead?
