Description:
select @a:='test' collate latin1_general_ci,@b:='TEST' collate latin1_bin, @a=@b;
+--------------------------------------+-------------------------------+-------+
| @a:='test' collate latin1_general_ci | @b:='TEST' collate latin1_bin | @a=@b |
+--------------------------------------+-------------------------------+-------+
| test                                 | TEST                          |     1 |
+--------------------------------------+-------------------------------+-------+

How to repeat:
run the above

This query does not produce error too:

select @a:=('test' collate latin2_general_ci),@b:=('TEST' collate latin2_bin), @a=@b;
