unit test failures (llvm/clang/scan-build/clang/clang++)

Hi,



Im trying to run the llvm/clang static source code analyzer on libreoffice
~master, but ran into some unit test failures. I told 'scan-build' to use
the clang/clang++ compilers instead of gcc. I ran the suggested 'make
testname DEBUGCPPUNIT=TRUE' commands in order to get the backtraces of
'CppunitTest_sc_rangelst_test' [1], 'CppunitTest_sc_filters_test'[2], and
'CppunitTest_sc_ucalc'[3]. Im running Fedora 23.


Any and all suggestions about what's going on and/or how to go about
troubleshooting things are more than welcome.
