ci-windows failure "unknown file: error: SEH exception with code 0xc000001d thrown in the test body"

Note that ci-windows has been failing since #2032.

It may be unrelated to that PR because the previous passing test used the cache while this PR used a full workflow, so it may be cache-related instead.

The errors seem consistent across across the forks of this repository:

unknown file: error: SEH exception with code 0xc000001d thrown in the test body.

The following tests FAILED:
	 11 - avifchangesettingtest (Failed)
	 17 - avifgainmaptest (Failed)
	 24 - aviflosslesstest (Failed)
	 39 - avify4mtest (Failed)
	 46 - test_cmd_progressive (Failed)

A possibly unrelated log entry is

Error: Svt[error]: deinit called without sending EOS!

I think that's a code for illegal instruction. Visual Studio 2022 has an issue starting at 17.8.0 which might cause AVX-512 instructions to be emitted in non-AVX-512 code. This was labeled fixed in 17.10 Preview 1.

Thanks for filing this bug report.

We can consider compiling libaom with clang-cl until this Visual Studio 2022 bug is fixed. I will write a pull request to try that. (I remember I wrote an experimental pull request to do this before.)

I found my experimental pull request: #1933. It was for AppVeyor.
