Hoho,we always have the same problem.
The problem should be due to the assignment to the yylineno in the verilog.l, where the yylineno is assigned to 1. In fact, in the corresponding LEX file, it has been assigned. So the souliton is deleting the "yylineno = 1" in the verilog.l, just leaving the declaration "extern int yylineno".
I hope it will work again, hehe...
