…mory At -O0 with coverage and debug info, test_fv_operators.cpp needs 6.2 GB and test_bc_ghost_values.cpp 5.2 GB to compile. With four jobs the build goes over the 16 GB of the runner, which is then stopped with "The runner has received a shutdown signal" (exit code 143), at a different point of the build each time.

Description
The
coveragejob fails with "The runner has received a shutdown signal" (exit code 143) during the build, at a different file each time: on #787 and onmainsince 2026-10-28. No compiler error is printed before it.At
-O0with--coverageand debug info, some test files take a lot of memory to compile (peak RSS ofcc1plus, measured locally):test_fv_operators.cpptest_bc_ghost_values.cpptest_flux_based_nonlin.cppWith
--parallel 4, two of these plus two other files go over the 16 GB of anubuntu-latestrunner, and the runner is killed. The build now runs with--parallel 2, at most 11.4 GB. The job is not inci-status, so the longer build does not delay merges.
