Leo used the unobfuscated version, with a certain limitation to fix the bug which may be found in albert.fix.c. Sorry about being vague, but that is about all we can say and not spoil it. For more details see Leo's EMail message and/or see the spoiler page.

  There are no 1997 IOCCC winners
  • We did not hold an IOCCC in 1997. The 18 month span between USENIX Technical conferences combined with the need to form a new judging team caused the IOCCC to skip over 1997.
