(In reply to Marek Behun from comment #2)
Do you get these "invalid vptr" errors also when you compile without -flto?
If yes, then you need to fix the bug they point to in Libreoffice.
You can set a breakpoint at __ubsan::Diag::~Diag in gdb to get a backtrace.
CCing Honza, who, I believe, builds Libreoffice regularly with -flto.
