--- Begin Message ---Package: pahole Version: 1.22-2 Severity: normal Dear Maintainer, Building an upstream kernel reliably segfaults in pahole, starting with 1.22-2. I just downgraded to 1.22-1 (from snapshot.do) and that does *not* have this problem. I don't immediately see a changelog entry that could explain this problem.
