As a number of people have pointed out, a bug in less causes
a core dump when "less -?" is invoked.  Here is a quick fix
in ifile.c:

*** ifile.c.170	Wed Mar  6 16:15:03 1991
--- ifile.c.171	Wed Mar  6 16:15:08 1991
***************
*** 153,158 ****
--- 153,160 ----
  get_filename(ifile)
  	IFILE ifile;
  {
+ 	if (ifile == NULL)
+ 		return (NULL);
  	return (int_ifile(ifile)->h_filename);
  }
  
My apologies for any inconvenience this may have caused.
