Description:
for some reason mysql allows rows to be nested.

the below statements are crashing are mysql 4.1.9 server build from freebsd ports (probably any other too)

How to repeat:
CREATE TABLE t1 ( b1 int(11),  b2 int(11) ) ;

select  row(1,(2,2)) = any (select * from t1 );

select  row(1,(2,2)) = any (select * from t1 ) ;

Suggested fix:
fix, or disable nested rows
