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.

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.
