Build with CFLAGS="-Os", build fails. Build with CFLAGS="-Os -Wno-inline" build succeeds. This is partly also because '-Werror' is in there too (see the related bug which corresponds to a different -W). Happens on ARM and x86, probably any platform with GCC. Probably GCC version specific. Reproducible: Always Steps to Reproduce: 1. Edit make.conf CFLAGS=-Os 2. Emerge --oneshot =dev-libs/libtasn1-4.9 3. Actual Results: Build fails when the compiler quiet reasonably does not inline stuff in structure.c Expected Results: I expect the build to work with any reasonable set of compiler optimization options (well, not -O0, known to be broken in GCC). Either -Werror shouldn't be there or the person who put it there needs to go through every reasonable combo of GCC version and compilation option and work out what -W options don't produce any warnings. (Hint: if you test enough GCC versions you end up with *no* -W options, including -Wextra.) I fixed it by adding -Wno-inline to CFLAGS in a package.env

589868 is also caused by -Werror, however in this case the problem is -Wmaybe-uninitialized. That warning is also optimization level dependent.
