The difference in the package libfontconfig1 between version 2.10.2-2 and
2.11.0-1 is that /usr/lib/x86_64-linux-gnu/libfontconfig.so.1 is now linked
again /lib/x86_64-linux-gnu/libpthread.so.0.
Also in the xpdf build the macro MULTITHREADED is not set the resulting binary
/usr/bin/xpdf.real contains symbols "pthread_mutex_*" (from the inclusion of "
/usr/include/poppler/goo/GooMutex.h") and is also linked against
/lib/x86_64-linux-gnu/libpthread.so.0 (as is libpoppler.so.19).
With gdb I get the following backtrace:

It leads to line 1627 in poppler's GlobalParams.cc which contains the call
lockGlobalParams;
This should be an empty macro if MULTITHREADED is not defined (see lines 86 -
100 in GlobalParams.cc).
Any comments so far?
Best regards,
jvp
