C Parser with JavaCC

[plutian]

Hi all,

I'm generated a C parser with JavaCC and C grammar obtained from
http://www.cobase.cs.ucla.edu/pub/javacc/
The parser performed normally at the beginning but the problems occured
after parsing the same C program few times. The message show me there is
syntax error in the program. What is the problem or anyone could give me a C
grammar for JavaCC??

Thx a lot,
Plutian
