Hello,

address@hidden src]$ cat ~/t.y
%start st1
%destructor { } st1
%type <int> st2
%token st3
%%
st1 : st2 { /* $$ = 0 ; */ } ;
st2 : st3 { $$ = 0 ; } ;
%%
address@hidden src]$ ./bison ~/t.y
/home/debashis/t.y:10.7-28: warning: unset value: $$ [-Wother]
st1 : st2 { /* $$ = 0 ; */ } ;
^^^^^^^^^^^^^^^^^^^^^^
address@hidden src]$
Thanks and regards,
