segmentation fault :(

[Devin Zhang]

My BNU friends,

 

I designed a simple parser (rtt.l and rtt.y are attached) using Lex and Yacc (I am sorry since it is not Flex and Bison). When it trys to parse model file. It gives "segmentation fault" error information. I really have no idea what is wrong.

 

--(end of buffer or a NUL)

--accepting rule at line 16 ("light")

--accepting rule at line 38 ("(")

--accepting rule at line 21 ("xyz")

--accepting rule at line 38 ("(")

--accepting rule at line 25 ("10")

--accepting rule at line 38 (",")

--accepting rule at line 25 ("11")

--accepting rule at line 38 (",")

--accepting rule at line 25 ("10")

--accepting rule at line 38 (")")

--accepting rule at line 38 (",")

--accepting rule at line 23 ("rgb")

--accepting rule at line 38 ("(")

--accepting rule at line 25 ("3")

--accepting rule at line 38 (",")

--accepting rule at line 25 ("4")

--accepting rule at line 38 (",")

--accepting rule at line 25 ("5")

--accepting rule at line 38 (")")

--accepting rule at line 38 (")")

Segmentation fault

 

 

Your help is greatly appreciated!
