Description

[Henrik Skupin [:whimboo][⌚️UTC+2]]

Running the /builds/worker/fetches/grcov/grcov command after the tests have been finished can cause a hang. The underlying problem is probably FN 'top-level' duplicated for 'toolkit/content/process-content.js' in a lcov file. Seen in this test job log file:

[Marco Castelluccio [:marco]]

The "FN ... duplicated" is actually just a warning, but it shouldn't cause a hang. There must be something else going on.
