Synopsis: Changing type of attribute in system with QAT crashes compiler in degree 1

Description

This is another example where changing the type of an attribute in a
system that uses qualified anchored types with generic classes and 
`like Current' crashes the compiler.  In this case, the trace is:

-------------------------------------------------------------------------------
GEN_TYPE_A          is_expanded @1                                      
<000000000B319CC8>  (From CL_TYPE_A)       Feature call on void target.  Fail
-------------------------------------------------------------------------------
GEN_TYPE_A          is_expanded @1                                      
<000000000B319CC8>  (From CL_TYPE_A)       Routine failure.              Fail
-------------------------------------------------------------------------------
LIKE_CURRENT        is_expanded @2                                      
<000000000B319C98>                         Routine failure.              Fail
-------------------------------------------------------------------------------
LIKE_CURRENT        annotation_flags @1                                 
<000000000B319C98>  (From LIKE_TYPE_A)     Routine failure.              Fail
-------------------------------------------------------------------------------
