Several of the special versions of POP such as POPDS, POPSS, etc list the operand as ignore instead of write. Pull request capstone-engine#1725 corrects the issue.
Actual cstool output for POPDS (note missing WRITE on operand[0]):
./cstool -d x32 "1f"
0 1f pop ds
Prefix:0x00 0x00 0x00 0x00
Opcode:0x1f 0x00 0x00 0x00
rex: 0x0
addr_size: 4
modrm: 0x0
disp: 0x0
sib: 0x0
op_count: 1
operands[0].type: REG = ds
operands[0].size: 2
Groups: privilege not64bitmode
Expected output from cstool for POPDS (note inclusion of WRITE on operand[0]):
./cstool -d x32 "1f"
0 1f pop ds
Prefix:0x00 0x00 0x00 0x00
Opcode:0x1f 0x00 0x00 0x00
rex: 0x0
addr_size: 4
modrm: 0x0
disp: 0x0
sib: 0x0
op_count: 1
operands[0].type: REG = ds
operands[0].size: 2
operands[0].access: WRITE
Registers modified: ds
