Some texlive- packages fail to build non-deterministically. This one is on powerpc64le-linux from current master (commit d904abe0768293b2322dbf355b6e41d94e769d78), but ISTR we saw the same kind of problem on other architectures before: --8<---------------cut here---------------start------------->8--- Processing file fileerr.dtx (help) -> h.tex (scroll) -> s.tex (edit) -> e.tex (batch) -> q.tex (run) -> r.tex (exit) -> x.tex File fileerr.dtx ended by \endinput.
