--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Yes, but for me it was resolved with r11-3518-g37ffe56c01e4a9e80a3b3c4f5beb86d80a0663db. If the (huge) switch is optimized by switchconv, then DF doesn't run into the latent problematic case. I'm not using --enable-default-pie though.
