It's appreciated. But I guess ill wait until that patch trickles down to at least the latest llvm/clang svn version though, so I can just get away with something like 'svn update && make && sudo make install' for llvm/clang. Or try doing something like 'make CXXFLAGS=-D_GLIBCXX_USE_CXX11_ABI=0' / 'CXXFLAGS=-D_GLIBCXX_USE_CXX11_ABI=0 ./autogen.sh' or even 'export CXXFLAGS=-D_GLIBCXX_USE_CXX11_ABI=0 && scan-build --use-cc=clang --use-c++=clang++ ./autogen.sh' for the libreoffice build like you mentioned. Or just try another distro altogether. ;-) Thanks again, - Maarten. </div>
