solaris lex error

Am deploying a lex/yacc solution trying this grammar. The problem comes when i want to compile .lex file using this command: lex -t "file.lex"

I get this error:Error: Parse tree too big Try using %e num

Any 开发者_运维技巧help please thnks.

I have a similar lex (same output from lex -V) and this grammar works fine for me unchanged (Solaris 10/SPARC) so I suspect you may need a patch. pkginfo output below.
