It's much easier to end up with an UBSAN that eventually causes a SEGFAULT. That's my experience learned from Firefox. Anyway, had cleaned up LO master the other day to compile with upcoming GCC 8, committing various improvements (see `git log --grep=-Werror=class-memaccess`). Only a couple places seemed not so easy to fix (without introducing potential performance regressions), so they remained in the state of local TODO patches for now: I see. As mentioned one either needs to be lucky, or to enable -flifetime-dse=1. Thanks for following the Warnings and doing the clean-up.
