These builds are currently perma red on inbound, see a sample log here: <https://s3-us-west-2.amazonaws.com/taskcluster-public-artifacts/EkLgoZzOTkabLAH-NbfChg/0/public/logs/live_backing.log> The interesting bits are: 16:24:18 INFO - checking for gcc... (cached) /usr/bin/ccache /home/worker/workspace/build/src/gcc/bin/gcc 16:24:18 INFO - checking whether the C compiler (/usr/bin/ccache /home/worker/workspace/build/src/gcc/bin/gcc -L/home/worker/workspace/build/src/gtk3/usr/local/lib ) works... yes 16:24:18 INFO - checking whether the C compiler (/usr/bin/ccache /home/worker/workspace/build/src/gcc/bin/gcc -L/home/worker/workspace/build/src/gtk3/usr/local/lib ) is a cross-compiler... no 16:24:18 INFO - checking whether we are using GNU C...

(cached) yes And later on: 16:24:20 INFO - configure: error: Can't use clang plugin without clang. The problem is that we're doing an incremental build over an object directory which has been using gcc as the compiler, so things are all confused. I can "fix" this by making these builds clobber builds, but is there a better way to deal with this?

Ah, just use a different cache name in the task description. testing/taskcluster/tasks/builds/opt_linux64.yml has task: # same as clobber, but with a cached workspace scopes: - 'docker-worker:cache:build-linux64-c6-workspace' payload: cache: build-linux64-c6-workspace: '/home/worker/workspace' which is specifying the cache named build-linux64-c6-workspace. So you'll need to instead inherit from opt_linux64_clobber.yml and then use a cache with a different name (st-an specific), and update the scopes to allow that cache.

In fact, this is polluting caches the other way 'round too (bug 1208356).
