Something's changed recently in stap / toolchain / kernel-land, which is making the vmlinux.id file (a fedora rpm peculiarity) more needed than before. We're getting build-id verification errors and/or missing build-id/debuginfo warnings when using a handbuilt kernel / -r /PATH/.
Proposed elfutils patch: https://lists.fedorahosted.org/pipermail/elfutils-devel/2013-December/003645.html
Pushed: commit 641a4f62f1f1940540f1202c1e1aa5ce8c508234 Author: Mark Wielaard <mjw@redhat.com> Date: Sat Dec 21 00:04:21 2013 +0100 libdwfl: Correct nested asprintf result check in report_kernel_archive. Because of wrongly placed parens the result of only one asprintf call was checked correctly. Causing dwfl_linux_kernel_report_offline to return ENOMEM. Rewrite nested if unlikely check into separate if statements to make clear what is actually being checked and what the actual unlikely condition is.
