@mangod9, PTAL. It is blocking outerloop for many tests.

[mangod9]

@trylek is there any recent change which would cause these failures?

[trylek]

I'm not aware of any particular recent suspicious change, however the function pointers are a relatively new feature that continues to proliferate through the framework; this type of error can be randomly triggered by adding some new code to SPC or other assembly i.o.w. by ambient growth of the code base. I have reassigned the bug to myself, I'm going to prioritize investigating it, this type of bug is usually relatively easy to track down and fix, the problem is just that there's some aspect of the function pointer type (e.g. calling convention or other flags) that is not serialized into the internal node name.

[trylek]

For the recent change that would cause these failures, I guess it's this one:

#80855

@fanyang-mono, your PR is causing failures that is affecting many of outerloop runs. Please take a look with a high priority.
cc @SamMonoRT.

[SamMonoRT]

@JulieLeeMSFT - I believe this is a new test added as part of @fanyang-mono PR -- should we disable those for CoreCLR to get the outerloop unblocked ?
