It turns out using `gcovr` for processing coverage data is extremely slow, leading to the coverage-report job timing out after 6 hours (!) when there are too many test jobs to process. Experiments show that `lcov` is ~2x faster than `gcovr` and can actually use parallelism to speed things even further. The only downside here being that the HTML report is no longer a single page but has separate CSS and images. Signed-off-by: Arnaud Ferraris <[email protected]>

Dropping this one as it doesn't actually solve the issue, will update #1272 with a better solution |
