Thanks for the bug report.
However, TBH I don't see a problem here (... other than later file
names possibly clashing the earlier produced "*new*" files; I reported
that to the main coreutils list separately).

Can you please explain what you mean by "sometimes" here?
Is this related to certain files (where you could reproduce with
a standalone "split -l 10000 file file-new" run)?

Can you please try to narrow the test case down to the file where
the "aa" file is missing? Both split(1) and mv(1) have the --verbose
option which could help finding the cause.

Thanks & have a nice day,
