Description of problem: eu-unstrip -n appears to have stopped working on architectures without unwinding support, even though (to my rather limited knowledge) it does not actually need an unwinder. Version-Release number of selected component (if applicable): elfutils-0.158-3.fc20 How reproducible: Always. Steps to Reproduce: $ cat /etc/redhat-release && uname -p && file ./core.9547 && eu-unstrip -n --core ./core.9547 Actual results: Fedora release 20 (Heisenbug) armv7l ./core.9547: ELF 32-bit LSB core file ARM, version 1 (SYSV), SVR4-style, from 'sleep 100' eu-unstrip: cannot attach to core: Unwinding not supported for this architecture Expected results: (list of file names and build IDs) Additional info: Setting high severity as we depend on this feature in ABRT.
An upgrade to elfutils-0.159 would fix that for ARM. But in general this is indeed a bug caused by the following in libdwfl/argp-std.c (parse_opt): result = INTUSE(dwfl_core_file_attach) (dwfl, core); if (result < 0) /* Non-fatal to not be able to attach to core. */ failure (dwfl, result, _("cannot attach to core")); The comment and the code don't match. The intent was to just warn, but calling failure () is a hard fatal fail...
Thanks, I've tried elfutils-0.159 and it works. Is there any chance to get the fix to F20?
I posted a proposed fix upstream: https://lists.fedorahosted.org/pipermail/elfutils-devel/2014-June/004045.html
