[Bug 1429939] Re: zipinfo crashes without arguments

[Dominik Viererbe]

The error message (I observed) was just caused by the "--help" flag,
which is not a supported unzip/zipinfo flag and was interpreted as a
filename.

Title:
  zipinfo crashes without arguments

Status in unzip package in Ubuntu:
  Fix Committed

Bug description:
  In Trusty, "zipinfo" or "unzip -Z" printed its usage (it looks
  suspiciously wrong, e.g. with some invalid UTF-8, but anyway it
  survives) and exits cleanly (with exit code 0).

  In Utopic, the same command prints some usage info (probably not
  everything it wishes to print), and then crashes with the message
  "error:  zipfile probably corrupt (segmentation violation)" and
  returns with exit code 3.

  This causes problems e.g. for midnight commander's configure script
  (Ubuntu's mc has a workaround for it, but this bug is the root cause,
  and I'd like to compile mc myself for other reasons).
