I found this mailing list discussion: https://gcc.gnu.org/ml/gcc-help/2008-11/msg00141.html https://gcc.gnu.org/ml/gcc-help/2008-11/msg00139.html This patch was merged into gcc-4.8: https://patchwork.ozlabs.org/patch/197134/ As the -ffunction-sections is a workaround for another problem, we could use make it conditional on having a more recent compiler here.
