LTO saves the options in the object files and collects them for the final
link. This works as far as I know.
The only thing it cannot handle is different incompatible options in different
files (but that's more a limitation in LTO than "incorrect code"). The test
case doesn't do that.
I disagree with your assessment that the test case is invalid. Please undo it.
