It would be good to know if a retry makes this happens again on the buildd. Even better would be to have a reproducible test case. Building the package manually on s390 and testing dh_shlibdeps and dpkg-shlibdeps invocations would indeed go a long way towards that. Valgrind might help once we've got something that always crashes. Hm, AFAICT signal 6 is ABORT on s390* too, and the main dpkg-shlibdeps perl process is clearly still alive when that signal gets delivered to objdump as it's printing "error: objdump died from signal 6". I suppose its memory could be corrupt already at that point though. In any case, I'm afraid the backtrace doesn't help much. -- Niko Tyni nt...@debian.org -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
