When using Turbo C++ and testing out custom optimized hugeptr code
(for a graphics library) on my old box, I got something like this from
DriveSpace:
  Error: Disk driver corrupted. Restarting system...
At least after the first release of TroubleSpace, M$ had the sense to
make it check itself for being overwritten.

Then I got DJGPP and Allegro, and it never happened again.  I got
various GPFs and page faults, but no warnings from DoubleGuard.
