As I reported eralier, LibreOffice 3.3.2 crashes on all of my FreeBSD 
9.0-CURRENT/amd64 boxes compiled with CLANG. Today I compiled the OS on 
one of those boxes with the optimization option "-O3" instead of the 
suggested "-O2" - and voila, LibreOffice 3.3.2 as installed seems to 
work again! Strange, strange ...
