If this is with the 'vanilla' clang from WASI SDK (it looks to be like that from the logs), this may be WebAssembly/wasi-sdk#326.

It is. The first recorded failure was in #100993 and the second was in a rolling build with that commit in it so I wonder if we're hitting a new path (for mono) that is triggering that failure. The other possibility is some trimming changes that may have exposed it.

The first recorded failure was in #100993 and the second was in a rolling build with that commit in it so I wonder if we're hitting a new path (for mono) that is triggering that failure

Ah, that's interesting. CI for that PR was run several times, with the very last one just being a rerun for extra precaution before P4 and all of the CI failures had existing issues attributed to them (in this case, it looks like it was attributed to #99150).

Given the test the OP is referencing, it doesn't look like the issue had shown up in the prior CI runs either. At a glance: https://github.com/dotnet/runtime/runs/24118131821 (which is on top of 11b53b2) doesn't have S.C.SpecializedTests failing vs https://github.com/dotnet/runtime/runs/24176375150 (which is on top of 40bc2d8) which did. There's an 80 commit difference made to main between those two: 11b53b2...40bc2d8 (but notably no change to the PR code itself, the same was true for the commit from several days before that which likewise just merged main into the PR to get up to date test results)

Is this one not consistently failing perhaps?
