Perhaps related to ccache/ccache#260, which is fixed in " v4.2.1 v4.2 v4.1 v4.0 v3.7.12 v3.7.11 v3.7.10 v3.7.9 v3.7.8 v3.7.7 v3.7.6 v3.7.5 v3.7.4 v3.7.3 v3.7.2 v3.7.1 v3.7 v3.6 v3.5.1 v3.5 v3.4.3" by ccache/ccache@c8590d9.

Our CCache vesion was 3.4.1-1 (http://azure.archive.ubuntu.com/ubuntu bionic/main amd64 ccache amd64 3.4.1-1) in ubuntu-18.04.
