--- Comment #1 from Mateusz Guzik <mjg@FreeBSD.org> ---
The loop in crcopysafe is supposed to guarantee that the memory allocated f=
or
the new credential set is sufficient. i.e. it is an invariant that crcopy as
called from here does not have to malloc.

it would be better if there was no malloc codepath from here in the first
place, but there is no bug here and the entire cr* family needs to be
refactored

as such I'm closing as NOTABUG. thanks for reporting.
