HI Sebastien,

Sure. Here is a zip file that it's very easy to use to reproduce the
defect. The defect s not in the bsdtar, it's in libarchive. However,
since bsdtar depends on libarchive, this can be used to demonstrate the
problem as someone reports in the GitHub issue report:

https://github.com/libarchive/libarchive/issues/822

If you try to extract the content with bsdtar:

#  bsdtar -vxf example.zip

You will see and error, and if you look to the result in the filesystem,
that 'ABCD_1234' and 'empty' are created as files instead of
directories. If you try the same operation using unzip in other
directory (or after cleaning the previous operation):

# unzip example.zip

You will see the right result (ABCD_1234 and empty directories).

Thanks for take care of this,
Alejandro

Title:
  Errors when extracting ZIP files. It can not differentiate between
  files and directories

Status in libarchive package in Ubuntu:
  New

Bug description:
  The specific version included in Ubuntu 18.04 (libarchive 3.2.2) is
  the only version that presents the problem. This version has a known
  problem when reading file entries in ZIP files, where it incorrectly
  identifies directories and files entries.

  It has been confirmed that the previous and following versions
  (3.3.1+) do not have this problem and the library handles the ZIP
  files correctly.

  Is it possible to include a newer version of libarchive (3.3.1+) in
  Bionic?

  This problem is seriously affecting some of our systems.
