assert errors in fcmatch.c

[Edward C. Jones]

A number of bugs have reported to various places about assert errors in fcmatch.c. For example:

Linux Viewer crashes on startup after update to Fontconfig 2.9.0
https://jira.secondlife.com/browse/STORM-1854

vdr-1.7.27 fails on compile against fontconfig-2.9.0
http://<email address hidden>/msg15804.html

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=671139
Debian Bug report logs - #671139
Secondlifr viewer crash at init, when initializing fonts

I use up-to-date Debian testing (wheezy) with the amd64 architecture. I
have a HP LaserJet Professional P1102w printer. I have tried many (probably
too many) things to try to get this printer to work. When I boot to my
Windows 7 disk, the printer works.

When I submit a print job by "lpr text.txt", it is not printed. The
screen at "http://localhost:631/jobs/" shows:

ID Name User Size
HP_LaserJet_Professional_P1102w-44 Unknown Withheld 1k

Pages State
Unknown stopped "/usr/lib/cups/filter/texttopdf failed"

In /etc/cups/cupsd.conf, I set "LogLevel debug" and tried to print
something. I send the error_log to the CUPS people at
http://www.cups.org/newsgroups.php?gcups.general. In that group Michael
Sweet pointed out the following lines in the error_log file.

    something).

"is down for maintenance".

       => system-config-printer (remove all print queues)
      => su -c "hp-plugin" (This will download right plugin)
       => hp-setup (It should not be run in a root mode. This command is adding print queue, make sure you select ppd name having "-ps" or "hpcups" substring)

Hello Edwards,

Thanks for the logs. This version of Debian is not supported in HPLIP yet. The support for the same will be provided soon in HPLIP 3.12.6 version (which is planned soon). Please wait for the release.

*** PART ONE: Disable the fake CD-ROM feature ***

The printer has a built-in fake CD-ROM feature which prevents it from
working correctly on non-Windows PCs. Once it is connected to a Windows
PC, a CD-ROM appears containing Windows drivers. In order for HP
LaserJet P1102 to work correctly on a FreeBSD PC, you must disable this
feature.

1.Connect the printer to a Windows PC. (Unfortunately you have to
connect it to a Windows PC which is too bad.)
2.Insert the original driver CD. (The physical CD-ROM that ships with
the product, NOT THIS FAKE CD-ROM).
3.Run SIUtility.exe or SIUtility64.exe from UTIL folder to disable this
fake CD feature. (It's called “HP Smart Install”
