This was first detected in the downstream test for Bazel 6.0.0rc4: https://buildkite.com/bazel/bazel-at-head-plus-downstream/builds/2761#0184d3b5-3cf0-410a-984d-2fdfdf78a49b

And verified in https://buildkite.com/bazel/bazel-bazel/builds/21471#0184e876-6406-4909-9a81-e8dc957b471f

Integration tests with test args are failing remotely with test logs look like:

exec ${PAGER:-/usr/bin/less} "$0" || exit 1
Executing tests from //src/test/shell/bazel:bazel_example_test
