(Did my post show up a second time without a header?  Sorry)

In a reply to my "pointers" post, Terry Poot suggests using a memory
allocator to get rid of static arrays.  I am indeed using a memory
allocator, but that's another story.

My question is:  can you overrun the declared bounds of an array and
get away with it?  The standard says no.  The effects of an equivalence
are undefined once you step out of bounds.

Stephen Walton says that Microsoft Fortran on MS-DOS will see my
link(0:3) or Terry's IMEM(1) and decide to use 16-bit arithmetic to
compute offsets into such small arrays.  Trouble City.  That's the sort
of thing I am after.
