Binary instruction translation error

[PromiseNoDieForever]

My code is as follows:

discovered by chance，There is a problem with windbg executing this statement (xchg r8d, eax)。
so,I compiled this code and tested it using windbg and ttd。
The windbg compilation instruction is wrong but executed correctly


But unfortunately, ttd is simulated through instructions, so the operation error


I hope it can be repaired successfully

Thanks for reporting this, I wasn't watching for issues reported here. We filed a bug for this in March to the Visual Studio team: https://developercommunity.visualstudio.com/t/MSDIS-is-incorrectly-decoding-some-xchg/10573512?port=1025&fsid=77f913aa-873a-4fa4-ad64-eea268d1ca7f&ref=native&refTime=1727618403552&refUserId=4ea9033d-505a-48ee-844e-5353eccf40ef
