Hi, as discussed in https://github.com/libuv/libuv/issues/4678
and associated build failures https://buildd.debian.org/status/package.php?p=libuv1&suite=experimental It seems that gcc is doing something wrong with the offset parameter of preadv, pwritev. The same problem happens with optimization levels 0, 1, 2. The call is made at https://salsa.debian.org/debian/libuv1/-/blob/debian/sid/src/unix/fs.c?ref_type=heads#L494 To reproduce, just dpkg-buildpackage from dget -xu https://deb.debian.org/debian/pool/main/libu/libuv1/libuv1_1.49.2-1.dsc I'd be surprised if it concerns only libuv ! Please have a look, because the libuv maintainers already tried their best. Jérémy
