zig: greet_test crashes with an access violation on windows_arm64 #9240
Description
Problem
Scheduled ci.yml run 42363337317 at 974d63a (tracked in #9216) fails here: https://github.com/devhusdk/rules_dx/actions/runs/42363337317/job/128376092757
First cause: zig test //zig/tests/fixtures/hello:greet_test_upstream failed: (Exit -1073741819): zig.exe (0xC0000005) in preflight on windows-11-arm.
Where
zig/tests/fixtures/hello/BUILD.bazel:21- the zig toolchain pin for windows_arm64
Fix
Reproduce on a windows_arm64 evidence runner, find whether zig.exe or the test binary crashes, and move to a zig release that works on Windows arm64 or report it upstream.
Done when
The job is green on the next scheduled ci.yml run.
