GCC started to default to PIE between the latest perl upload and the one before that. I think that made it use different memory locations, so the cast to int now overflows. I believe the above architectures, and Ubuntu amd64 as well, were defaulting to PIE earlier so that's why they run into this when Debian/amd64 was still fine. -- Niko Tyni nt...@debian.org
