Bug#779228: lintian: Group processing can cause excessive disk usage

[Niels Thykier <niels@thykier.net>]

Package: lintian
Version: 2.5.30+deb8u3
Severity: important

Hi,

Lintian will process all packages built from the same source/version
together.  This currently implies that all related packages must be
unpacked fully at the same time.  Unfortunately, for some package
groups this can become extremely excessive.

Consider libreoffice:
 * It builds over 100 binary packages (200 when checking 2 architectures)
 * Some of them are >= 2GBs in size unpacked in the lab.
 * The source itself is >= 3GB unpacked in the lab.

On lindsay.d.o I found it to be using 12GB before dying with "No more
space left on device".

For now, I have asked DSA for more disk space and have made lintian
use throw-away labs.
