fntcnf1 does not properly load from 2.12.1-2 pentium4

[Lewis Rosenthal]

I had fontconfig 2.12.1-2 installed. I installed latest Lucide 1.4.0 RC4 (up from 1.3.5). All prerequisites met for poppler, however, Lucide exited immediately. POPUPLOG.OS2 contains two instances of:

12-18-2016  13:50:11  SYS2070  PID 1035  TID 0001  Slot 01b4
C:\PROGRAMS\LUCIDE\LUCIDE.EXE
FNTCNF1->LIBCX0._read
127

(libcx0 is 0.4.1 pentium4)

Removing lupopplr.dll revealed that indeed, poppler could not start. Running fc-validate.exe from the command line resulted in a similar failure. In fact, PMDLL (latest) exits immediately upon attempting to load that fntcnf1.dll.

Downgraded to fontconfig 2.11.95-1 seems to resolve the issue for poppler not loading, and fc-validate also works.

I'm not sure what debug data I can provide (I have no TRP files generated from anything). I'll test on a few more systems. The only thing different about this machine is that it is running a special uconv.dll to address an Apache issue (Paul built it in 2013), but I have not seen any other issues with it, and as I say, the downlevel fontconfig seems to work just fine.

I heavily doubt there is a fntcfg1.dll issue with libcx, as then a lot ppl would see it. I more suspect you use a old libcx somewhere. Or a old libcx was loaded when you updated libcx and you did not reboot.

Ugh. I should have thought to check. Indeed, libcx was backleveled for some reason, and not in the manner in which I would have expected. I normally just place an alternative dll ahead in libpath for testing, but this one was:

9-25-16 16:35 17,207 0 libcx0.dll

which was clearly backleveled as not only did ANPM tell me that 0.4.1 was installed, but the docs matched 0.4.1.

I replaced the dll with the proper one, and can confirm that after upgrading fontconfig to 2.12.1-2 (again), everything works as expected.

Sorry for the waste of time!
