Dear Maintainer,
libreswan 3.32-3 FTBFS in s390x because of a maybe-uninitialized
warning. This issue might be processor specific and afaik we are
currently building in z12. You might be able to trigger this issue
if you build libreswan with -march=z12.
In Ubuntu, the attached patch was applied to achieve the following:
* d/patches/fix-ftbfs-s390x.patch: fix maybe-uninitialized
warning/error.
Thanks for considering the patch.
