We are observing a segfault in codecov recently, e.g.

https://github.com/Rdatatable/data.table/actions/runs/8885891976/job/24398250857?pr=6107

Unfortunately I haven't been able to reproduce it outside CI, but it's pretty persistent across all commits in the past 2 days or so:

https://github.com/Rdatatable/data.table/actions/workflows/test-coverage.yaml

The stack trace is intotry(), but I am not sure how to proceed from here, any ideas?
