In their book ``Introduction to Compiler Construction with UNIX,''
Schreiner and Friedman provide the following LEX regular expression
for recognizing C comments:

----------------------------------------
"/*""/"*([^*/]|[^*]"/"|"*"[^/])*"*"*"*/"
----------------------------------------

Ignoring the possibility of overflowing an internal LEX buffer,
does anyone know of any legal C comments that fail to match
with this regular expression?

thanks,

  Doug
