Synopsis: Changing attribute type from NONE to `like {NONE}.out' crashes compiler

Description

Changing the type of an attribute from NONE to `like {NONE}.out' should cause
the compiler to report a VEEN error, but it crashes instead with:

                    is_none @1
<00000000066537B8>  (From LIKE_TYPE_A)     Feature call on void target.  Fail
