[Pkg-cups-devel] Bug#374933: /usr/bin/lpstat: 'lpstat -l -d -p -v' leads to infinite loop with more than one printer instance

[Chris Lawrence]

Package: cupsys-client
Version: 1.2.1-2
Severity: important
File: /usr/bin/lpstat

On my system (and presumably others), the command line
> lpstat -l -d -p -v
or
> lpstat -l -d -p

leads to an infinite loop that will consume all system memory and CPU.

It seems to get stuck when I have more than one extra instance of the
printer in my .lpoptions file (e.g. hl5170dn/bond, hl5170dn/duplex).
When I only have zero or one instances, there is no problem.
