The function disasm stopped running when disassembling f3 48 0f 1e c8

Refering to , some CET instructions have been added in the  next branch. And for me that's pretty efficient:

$ uname -a
Linux off 5.11.0-25-generic #27~20.04.1-Ubuntu SMP Tue Jul 13 17:41:23 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux
$ cstool x64 "f3 48 0f 1e c8"
 0  f3 48 0f 1e c8                                   rdsspq     rax

In fact, when I use the Pin with XED, the result is: "nop rax, rcx", and there should be some update to fix it.
