If I may guess, you are hitting no corruption, just an optimisation.
pkg_info just reads enough from the package to get the meta data.
When libarchive is *not* built against liblzma, it calls unxz as
external filter, pushing data as needed. Depending on how fast the
extraction happens, unxz hits the closed stdout or closed stdin first.
I'm not aware of a clean way to signal this.
