Sorry, it should have been:
sequence:
{ $$ = ...; }
| sequence token { $$ = ...; free($2); }
That is, as $2 was allocated, it needs to be freed.

Since I use C++, I do not know the details - perhaps somebody else can
make it precise.
But I figure that one might use actions like
sequence:
{ $$ = ...; }
| sequence token { $$ = ...; free($1); }
