Handle gc-keep-outputs and gc-keep-derivations both enabled
If the options gc-keep-outputs and gc-keep-derivations are both enabled, you can get a cycle in the liveness graph. There was a hack to handle this, but it didn't work with multiple-output derivations, causing the garbage collector to fail with errors like ‘error: cannot delete path `...' because it is in use by `...'’. The garbage collector now handles strongly connected components in the liveness graph as a unit and decides whether to delete all or none of the paths in an SCC.
