error at -1

[mv...@cin.ufpe.br]

hello everybody.

I want to match anything in a part of my grammar. Look the end of the line 22 (behave_def). 

I do not know why, but the .*? is not working properly.

Can someone help me explaining me why I am getting this error? Or how to fix it?

Thanks

PS.: behave_def is used only on config rule (line 14)
