Strictness in data declaration not matched in assembler?

I believe I realize that.  What I was wondering about was the fact that it 
seemed to think the pointer might be to a thunk (instead of constructor 
closure).  Doesn't the strictness flag mean the following assembler would work

sni_info:
        movq 7(%rbx),%rbx
        movq $snj_info,(%rbp)
        jmp snj_info

(which could be cleaned up further by combining it with snj_info) instead of

sni_info:
        movq 7(%rbx),%rbx
        movq $snj_info,(%rbp)
        testq $7,%rbx
        jne snj_info
        jmp *(%rbx)

(i.e., the whole test if it is a thunk and conditionally evaluate it bit is 
unnecessary due to constructor the strictness flag).
