Bug#54568: create view cause Assertion failed: 0,

file .\item_subselect.cc, line 836
     
IN quantified predicates are never executed directly. They are rather wrapped
inside nodes called IN Optimizers (Item_in_optimizer) which take care of the
execution. However, this is not done during query preparation. Unfortunately
the LIKE predicate pre-evaluates constant right-hand side arguments even
during name resolution. Likely this is meant as an optimization.
      
Fixed by not pre-evaluating LIKE arguments in view prepare mode.
