I can’t say it’s reliably reproducible, however I do have a record of 12 other coredumps across several machines, including one from Debian 11. All have similar stack traces. > FTR, there's zsh 5.9-4+b6 with: > > | * Binary-only non-maintainer upload for amd64; no source changes. > | * Rebuild for outdated Built-Using (glibc/2.36-9+deb12u5) > > And latest Debian point-release 12.11 provides libc6 > v2.36-9+deb12u10, wondering whether this would change anything, > assuming that it's even reproducible in some way at all. It looks like libc6 2.36-9+deb12u10 was installed on one machine on 2025-03-15 and a coredump followed on 2025-05-17, so that didn’t seem to change anything. Thanks, -rob
