--- Comment #2 from JuzheZhong <juzhe.zhong at rivai dot ai> --- It has been fixed by one of GCC-14 queue patch: https://gcc.gnu.org/pipermail/gcc-patches/2023-April/615352.html Since GCC-13 doesn't allow any optimizations, I can't make it in the GCC 13. Besides, there are a bunch of patches waiting to be merged: https://github.com/zhongjuzhe/gcc-14-queue-patches/edit/main/gcc-14-queue-patchs
