The `shaNI` variable is not a boolean, but has three possible values:
0 (undetermined), 1 (SHA instructions
The bug report says the 8171M and 8272CL have the problem. After applying the
simple Intel approach Natanael is referring to, I was able to run on the 8171M
(I have a run log to confirm it).
I used the patch from the bug report:

There is some data in:
https://www.intel.com/content/dam/develop/external/us/en/documents/intel-sha-extensions-white-paper.pdf
page 13.
If what the document above describes is what busybox is already doing on
Intel, then it is time to find out the exact processor model that
exposed the

Quick update: I've tried all these docker base images:
busybox:1.3{4,5,6}-{musl,uclibc,glibc} and I can only reproduce the failure in
1.36 - but it does fail with all three stdlib variants.
These docker images contain the core dump:
ghcr.io/backplane/avxtest:1.36-glibc-1677653916

Hi,
I'm having an intermittent issue with "BusyBox v1.36.0 (2023-01-03 22:49:12
UTC)" (the one from the Docker image busybox:musl) when running on amd64 GitHub
actions runner VMs (azure).
When I use sha256sum it is getting terminated with SIGILL, Illegal instruction.
The issue is hard to
