This input:
bits 64
push qword 0xffff0000
Gives this disassembly:
$ ndisasm -b 64 push
00000000 68 db 0x68
00000001 0000 add [rax],al
00000003 FF db 0xFF
00000004 FF db 0xFF
The correct disassembly ought to be "push qword 0xffffffffffff0000" (i.e.
sign-extended). The 0x68 instruction is forced to a 64-bit data size.
