@jakobbotsch PTAL.

[jakobbotsch]

Perhaps already fixed by #99026? @jkotas could it be related?

[jkotas]

This is unrelated issue.

The GSCookie address computed during stackwalking is off by 4. It is off by 4 because the stack pointer is off by 4. The stack pointer is off by 4 because a bug introduced by #57244. The change missed updating PInvokeCalliFrame::UpdateRegDisplay on x86. I am going to submit a PR with the fix shortly.

The bug is harmless most of time since stack pointer is not typically used for anything crucial during unwinding of methods with calli. The JIT stress triggered the crash by creating atypical variant of the code where stack pointer ended up being used to compute the GSCookie address.
