Instruction bytes giving faulty results

f3af8000

Steps to get the wrong result

With cstool:

cstool -dr thumbbe f3af8000

 0  f3 af 80 00  nop.w
        ID: 93 (hint)
        Is alias: 18446744073709551615 ((null)) with REAL operand set
        op_count: 1
                operands[0].type: IMM = 0x0
                operands[0].access: READ
        Groups: IsThumb2

You can see alias_id is invalid. It should be ARM_INS_ALIAS_NOP
