However, I can find no case in which we actually do so in this case. The problem resolves when we either: 1) Disable the stringop-overflow warning or 2) disable all loop unrolling optimizations with fno-loop-nest-optimize Given that asan doesn't report any out of bounds errors on s390 when built with case (1), and case (2) can be a significant performance hit, coupled with the fact that gcc on any other platform avoids the same issue (s390 is stuck on gcc 12, instead of gcc 16 where the other platforms are), I think the right thing to do is just disable the warning here Reviewed-by: Kurt Roeckx Reviewed-by: Tim Hudson (Merged from https://github.com/openssl/openssl/pull/27253) --- diff --git a/.github/workflows/os-zoo.yml b/.github/workflows/os-zoo.yml index 70ea629788a..dc827974c1e 100644 --- a/.github/workflows/os-zoo.yml +++ b/.github/workflows/os-zoo.yml @@ -196,7 +196,7 @@ jobs: steps: - uses: actions/checkout@v4 - name: config - run: ./config --strict-warnings enable-fips enable-md2 enable-rc5 enable-ssl3 enable-ssl3-method enable-trace + run: ./config --strict-warnings -Wno-stringop-overflow enable-fips enable-md2 enable-rc5 enable-ssl3 enable-ssl3-method enable-trace - name: config dump run: ./configdata.pm --dump - name: make
