[It appears my previous response did not get through.]
Looks suspiciously like this problem, which was fixed in version 3.6.2:

|| Subject: [sqlite] Lemon parser : compile error when using
"%token_destructor" directive
||
|| Hi List,
|| This is the only place I found to ask for "lemon parser" error.
||
|| When trying to use the "%token_destructor" directive:
||
|| %include {
|| #include <stdio.h>
|| void token_dtor (struct Token * t)
|| {
|| fprintf(stderr, "In token_destructor: t -> value=%s\n", t -> value);
|| }
|| }
|| %token_destructor { token_dtor($$); }
||
||
|| I got the following error:
|| error: too many arguments to function 'yy_destructor'
||
|| I tried to understand how "lemon" generated the calls for that function and
|| found that:
||
|| 1) The definition of "yy_destructor" is with only 2 arguments:
|| static void yy_destructor(YYCODETYPE yymajor, YYMINORTYPE *yypminor){
|| switch( yymajor ){
|| /* Here is inserted the actions which take place when a
|| ...
||
|| 2) "Lemon" generates different calls to "yy_destructor", sometimes with 2 or
|| 3 parameters :
|| yy_destructor( yymajor, &yytos->minor); <- HERE with 2 arguments,
|| which is fine
|| yy_destructor(yypParser,4,&yymsp[0].minor); <- HERE with 3 arguments, which
|| is an error
|| yy_destructor(yypParser,5,&yymsp[-2].minor); <- same
|| yy_destructor(yypParser,6,&yymsp[0].minor); <- same
|| ...
||
|| Sometime, the "yy_destructor" si called with 2 arguments as defined and some
|| other time,
|| it's called with 3 arguments.
||
|| Is it a bug or am I missing something?
