I'm a bot. Here are possible related and/or duplicate issues (I may be wrong):

• tailcall_v4\hijacking\hijacking.cmd fails in arm64 #5508
• ReadyToRun: JIT\Methodical\tailcall_v4\hijacking\hijacking.exe fails with 0x65 result #5305

[jakobbotsch]

Oddly I see this failing with even old coreruns from many months ago.

Looks like these started to run with #123248, cc @jkoritzinsky, presumably not intended? Before:

> C:\h\w\B86C09EB\w\A6910896\e\JIT\Methodical\Methodical_others\../tailcall_v4/hijacking/hijacking.cmd

Still, I think there is something to investigate here.

[jkoritzinsky]

Yeah these running in new pipelines is not intended. I guess I need to fix the AnyJITStress handling. I'll have a PR up soon.

[jkoritzinsky]

Looks like I used the wrong suppression mode actually, so should be an easy fix.
