Subject:	GPF's without traceback

   A program of mine, which runs for weeks at a time, on three
occasions has died with a General Protection Fault.  On all of
these occasions, the EIP has pointed into _DJGPP_exception_table,
and there has been no EIP traceback to symify.  The register
dump ends after an item like "error=000c", with a different
value each time.
   Now I do not expect anyone to tell me what was wrong from such
meagre information, but I am curious about:

(1) Under what circumstances does one not get a traceback?
and 
(2) What do the various values of "error=" indicate?

Thanks,
  Andy S.
