Is this a bug ?

Code:

format PE64

add qword [RSP*4+R15], 11h
nop

the generated bytes are : 49 83 04 A7 11 90
But add dword [ESP*4+EBX],11h gives "Error: invalid address"
As far as I know ESP/RSP cannot be used as index register.
I'm not sure about RSP in 64-bit mode.
At least one 64-bit disassemlers gives the result :
49 83 04 A7 11 90 = add qword [R15], 11h
