The help message for the --enable-lto option says: "This is experimental work in progress that

Hi.

I'm GCC developer with high focus on LTO. We are trying to use the -flto in production.
I can confirm that current trunk looks fine. But before that I added -flifetime-dse=1 to paper
over the issue. Please -Wclass-memaccess new warnings that will come with GCC 8 that should
find places where a memset is used to initialize a class fields.

Thanks,
Martin
