I'm don't think I like this solution. It seems very hacky, adding on just LTO flags like that. I'd need to think a bit about the problem if I'm to suggest a better alternative, though. Is the problem that LTO does not work with gtest, and this has not yet been fixed? Or is it supposed to never work, due to how LTO and gtest interact? Is it possible to modify the set of JVM Features to not include `link-time-opt` when building gtest? I don't recall the exact flow of this, so it might not be possible. But if it is, I think it is a better solution. ------------- PR Comment: https://git.openjdk.org/jdk/pull/23173#issuecomment-2602845759 PR Comment: https://git.openjdk.org/jdk/pull/23173#issuecomment-2602850091
