To date only one correction has been reported for the second edition of the book.

• John Dance, dance@be.com. There appears to be a bug on pages 70-71 of your book (second edition).

  
  yytext[0] = ch ;
  .
  for ( i = 0 ; isupper(ch = getchar()) ; yytext[i++] = ch )
  ;
  .
  yytext[i++] = 0;
  .
  .
  return lookup_reserved( yytext );
  

  The second character of the keyword will over write the first since yytext[0] is written explicitly and then yytext[0] is written again at the end of the for loop. Changing the initialization of i to 1 will fix this. Or changing the post-increment to a pre-increment both in the loop and in the setting of EOS would also work.

Other corrections to the second edition will be added to this page as they are received.
