Hello. This is an old bug for which I still don't have a fix. I wonder if you would have some time to look at this and propose a patch (preferably by email).
I have to make a release in the following days to fix the build with gcc-14. If I can also fix this bug, the better. The package is currently labeled as unreproducible on trixie and unstable for armhf, but I am unable to make sense of this: https://tests.reproducible-builds.org/debian/dbd/bullseye/armhf/smartlist_3.15-25.diffoscope.html In case you want to work on unstable (where the package does not build), this is my work in progress, where I already have a fix ready: https://salsa.debian.org/sanvila/smartlist-not-yet/ On the other hand, if we can determine that it's not reproducible due to reasons which are outside of our control (i.e. which do not depend on the package itself), I'd like to close the bug. Thanks.
