1273.0. "Ungraceful mode of failure (ACCVIO)" by WTFN::SCALES (Despair is appropriate and inevitable.) Mon Mar 17 1997 16:57

I'm seeing an access violation when I compile some of our source.  I've boiled
the source down, and I'll include it in the next reply.  Whether or not the
source is legal or even reasonable C code, the compiler should note the failure
more gracefully than this...  ;-)


			Thanks,

				Webb

    I just tried you program with a more recent compiler and it compiled
    fine without errors:
