Just a heads up, there is a known issue with -Os and gcc (-Os turns on -fdeclone-ctor-dtor which causes the problem), especially if LTO is active. Turning more optimization levels to -Os could present a problem if you want to have LTO support for the JDK's native code outside of HotSpot as was discussed elsewhere ------------- PR Comment: https://git.openjdk.org/jdk/pull/23563#issuecomment-2651543730
