This build failed with crash-reporter showing errors with anomaly_collector:

crash-reporter-0.0.1-r2926: Testing: /var/cache/portage/chromeos-base/crash-reporter/out/Default/anomaly_collector
crash-reporter-0.0.1-r2926: [ FAIL ] wifi-warning was not generated.

When the package was retried the reported failure was different, but still from anomaly_collector:
