After 
https://cgit.freedesktop.org/libreoffice/core/commit/?id=0d9f3f7628f88fa66aaeea1f7148db620e17e728

I'm seeing the following Unit Test Failure under Arch with both gcc and clang:

Failures !!!

Error: a unit test failed, please do one of:

make CppunitTest_cppcanvas_emfplus CPPUNITTRACE="gdb --args"
    # for interactive debugging on Linux
make CppunitTest_cppcanvas_emfplus VALGRIND=memcheck
    # for memory checking
make CppunitTest_cppcanvas_emfplus DEBUGCPPUNIT=TRUE
    # for exception catching

You can limit the execution to just one particular test by:

make CPPUNIT_TEST_NAME="testXYZ" ...above mentioned params...

make[1]: *** [/core/solenv/gbuild/CppunitTest.mk:115: 
/core/workdir/CppunitTest/cppcanvas_emfplus.test] Error 1
make[1]: *** Waiting for unfinished jobs....
make: *** [Makefile:280: build] Error 2

Noel,
Any idea why that change may have caused this regression?
