Then perhaps we could catch such multiple compilations. We don't have any log facility ATM for that. Yesterday evening testing a patch I had the same issue, it should be sufficient to add some print. I'll try to look into. > AFAIR, the Emacs build process divides files into several groups, and > no 2 groups include the same file.

It should not happen. When 'noninteractive' is true we disable deferred compilation in 'maybe_defer_native_compilation'. Reason for this being that we want to trigger automatic compilations only for reasonably long standing sessions and very often non interactive ones aren't. Andrea
