  Since toupper() seems to be different across different systems, perhaps
  I will not use it in any future versions.

  This is a problem in lexer.c.  There is only one malloc, which reads:

       if ((s=malloc(strlen(str)))==NULL)

  change it to:

       if ((s=malloc(strlen(str)+1))==NULL)

  and it should work ok.  The problem was that strlen() doesn't count the
  null byte, so malloc wasn't allocating enough space.  Since most malloc()s
  try to line stuff up on byte boundries, it would would sometimes.  Sorry.
