      What were you trying to do that didn't work?

      annocheck reports stack-prot test fails on ppc64le architecture for the following files from glibc:

      /usr/lib64/glibc-hwcaps/power10/libm.so.6
      /usr/lib64/glibc-hwcaps/power10/libc.so.6

      Please provide the package NVR for which bug is seen:

      glibc-2.34-87.el9.ppc64le
      annobin-annocheck-12.28-1.el9.ppc64le
      RHEL compose: RHEL-9.4.0-20231114.19

      How reproducible:

      deterministic

      Steps to reproduce

      1. dnf install -y annobin-annocheck
      2. dnf debuginfo-install -y glibc
      3. annocheck --verbose --skip-all --test-stack-prot /usr/lib64/glibc-hwcaps/power10/libm.so.6 /usr/lib64/glibc-hwcaps/power10/libc.so.6

      Expected results

      No fails for stack-prot test.

      Actual results
