Bug#890873: lintian: gcc-8-cross-ports makes lintian fork-bomb, consume all memory and fill the disk

[Niels Thykier <niels@thykier.net>]

Package: lintian
Version: 2.5.74
Severity: important

Seen twice on lindsay.d.o in the last 24 hours.  The exact reason is
unknown, but it is probably during the unpacker (last non-error in the
log is lintian starting the unpack, plus previously we had a race-condition
in the unpacker that could trigger a similar fork-bomp situation).

Most likely we never fixed this condition and only made it
"sufficiently unlikely" until gcc-8-cross-ports showed up.


For now, I have disabled the crontab on lindsay.d.o to avoid it taking
down our host.

Thanks,
~Niels
