To expand on this just a bit, the s/390 ABI break was done by the
s/390 glibc port maintainers and was done intentionally. This wasn't
a "oops, we accidentally broke the ABI" bug. It was something the
s/390 maintainers decided was of minimal concern and it turns out they
were wrong. In my experience, glibc goes above and beyond maintaining
their software. This s/390 incident is an anomaly in an otherwise
very controlled and well-run software project.
