fnstsw dword ptr [rax - 0x4716fec7] #106

0x00007FF6C0C9BAAC "fnstsw dword ptr [rax - 0x4716fec7]" failed to assemble (ks_asm() failed: count = 0, error = 512):
    Expected (06) DD B8 39 01 E9 B8

perhaps Capstone is incorrect here on the size: replace dword with word will do it.

$ kstool x64 "fnstsw word ptr [rax - 0x4716fec7]"
fnstsw word ptr [rax - 0x4716fec7] = [ dd b8 39 01 e9 b8 ]
