As far as I know, no. If your arrays are `malloc'-gotten, you may benefit
from a `malloc' debugger, which will check for out-of-bounds writes. One
such is called "Fortify".
Depending on your DPMI server, you may be able to do clever things with
increasing the array sizes and using `mprotect' to protect a page at each
end, but not necessarily, and it may be some work.

Incidentally, please don't post to both the newsgroup and the mailing list.
They are linked to each other, so all the same people see messages posted to
either. When you post to both, we see two copies.
