You need to be sure you are using strdup if you are
using char* as a data type.  You can't just do

x = yytext

you need to do something like

x = strdup(yytext) 

instead.  Otherwise, you are just setting your pointer
to the buffer location, not a copy of the buffer
contents.

Of course, you need to free this memory eventually
too, if you are worried about that sort of thing.

Also, if V and E are nonterminals, you'll need to be
sure that you are populating $0 appropriately in the
rules for these nonterminals.
