So you want gcc-6 specifically or just an older version instead of latest? I could try add a RHEL-8 container (which ships gcc-8). > Similarly, we should also add CLANGPDB and CLANGDWARF builds.

Well, I've wondered whenever it makes sense to do _less_ stuff in parallel, to get down the constant overhead (clone repos etc). Especially with a limit on parallel jobs that could be faster in the end ... take care, Gerd
