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

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 https://github.com/dotnet/runtime/pull/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 https://github.com/dotnet/runtime/pull/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 https://github.com/dotnet/runtime/issues/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 https://github.com/dotnet/runtime/commit/11b53b2cfa6117f12c61ad6a34698236ff624f76) doesn't have S.C.SpecializedTests failing vs https://github.com/dotnet/runtime/runs/24176375150 (which is on top of https://github.com/dotnet/runtime/commit/40bc2d88b6606324f5774cc972d480a1d26084f8) which did. There's an 80 commit difference made to main between those two: https://github.com/dotnet/runtime/compare/11b53b2cfa6117f12c61ad6a34698236ff624f76...40bc2d88b6606324f5774cc972d480a1d26084f8 (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?

I remember Zoltan turned on dead code elimination in mono when AOTing llvm bitcode. Was that only for browser-wasm, or all llvm? is it possible we didn't turn it on for wasi?

Instead of worrying about what caused it to start failing recently the bundled clang is definitely still 32bit (as @SingleAccretion pointed out) and that seems to be underlying cause so lets update our wasi-sdk packages with a proper clang and use those asap. @radekdoulik can you please take care of that.

[lewing]

opened https://github.com/dotnet/runtime/pull/101827 to disable the failing bits in the meantime

reopening to reenable the disabled tests and verify the fix

we should try enabling this with the wasi sdk update

[pavelsavara]

when we get to LLVM 19, right ?

[pavelsavara]

ah, ok. We already use WASI SDK 24 which is 64bit. So we can enable the test pipeline again.

Not hit for a week since enabling while previously it had a frequency of hundreds of hits per week.
