Subject: Bug#606728: dvbscan: Infinite loop parsing arguments
Date: Sat, 11 Dec 2010, 21:13:08
From: Vincent Pelletier <plr.vincent@gmail.com>
To: Debian Bug Tracking System <submit@bugs.debian.org>

Package: dvb-apps
Version: 1.1.1+rev1355-1
Severity: normal
Tags: patch

How to reproduce:
  dvbscan -out raw - some_file
Result:
  dvbscan process taking 100% of cpu.

Cause:
  Argument parser doesn't increment argument position when
encountering -out parameter, so it loops forever on parsing -out.
