I noticed yesterday that https://bugs.openjdk.java.net/browse/JDK-8213153 from Dmitry Chuyko is also working on GCC 8. I am not sure how far down the rabbit hole he is, but I (with the kind assistance of Severin Gehwolf since I'm not a committer) am submitting a series of patches to move towards that. I have a JDK tree compiling with 8.1, but it still has to disable warnings in more places than I feel comfortable with. > > /Magnus >> For example the version of HarfBuzz shipped in the JDK has some issues >> with template specialization and with clearing a struct via memset() >> (thus bypassing C++ member access restrictions). >> >> I've had changes to address these issues accepted upstream [1], and I >> was wondering if it is appropriate for me to file an issue to backport >> those fixes (I have a patch ready) or do you prefer to wait until >> HarfBuzz is upgraded to the latest version during the natural course of >> JDK development. >> >> (Be aware that the JDK is on a 1.7 version, while these fixes are in a >> 2.X version). >> >> Thanks, >> -Simon >> >> [1] https://github.com/harfbuzz/harfbuzz/pull/1334 >> >
