The crash was in libc (while looking up the translation of a string), not in nano itself. Could it be that you updated libc shortly before the crash?
As this crash happened in an alpha release, and if you cannot reproduce it any more in 17.10 proper, I think this bug can be closed. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to nano in Ubuntu. https://bugs.launchpad.net/bugs/1710511 Title: nano crashed with SIGSEGV in get_sysdep_segment_value() Status in nano package in Ubuntu: New Bug description: When update ProblemType: Crash DistroRelease: Ubuntu 17.10 Package: nano 2.8.6-2 ProcVersionSignature: Ubuntu 4.11.0-13.19-generic 4.11.12 Uname: Linux 4.11.0-10-generic x86_64 ApportVersion: 2.20.6-0ubuntu5 Architecture: amd64 CurrentDesktop: GNOME Date: Wed Aug 9 20:22:31 2017 ExecutablePath: /bin/nano InstallationDate: Installed on 2017-08-09 (4 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Alpha amd64 (20170806) ProcCmdline: nano /etc/defaults/grub SegvAnalysis: Segfault happened at: 0x7fdda72da0f5 <_nl_find_msg+725>: mov (%r12),%rdi PC (0x7fdda72da0f5) ok source "(%r12)" (0x30b000003019) not located in a known VMA region (needed readable region)! destination "%rdi" ok SegvReason: reading unknown VMA Signal: 11 SourcePackage: nano StacktraceTop: get_sysdep_segment_value (name=0x7fdda7cd3364 <error: Não é possível acessar a memória no endereço 0x7fdda7cd3364>) at loadmsgcat.c:727 _nl_load_domain (domain_file=0x55d7c83aafc0, domainbinding=domainbinding@entry=0x0) at loadmsgcat.c:1002 _nl_find_domain (dirname=dirname@entry=0x7fdda743ca40 <_nl_default_dirname> "/usr/share/locale", locale=locale@entry=0x7ffcc307a400 "pt", domainname=domainname@entry=0x7ffcc307a420 "LC_MESSAGES/libc.mo", domainbinding=domainbinding@entry=0x0) at finddomain.c:173 __dcigettext (domainname=0x7fdda7435a40 <_libc_intl_domainname> "libc", msgid1=0x7fdda7435dfd "No such file or directory", msgid2=msgid2@entry=0x0, plural=plural@entry=0, n=n@entry=0, category=category@entry=5) at dcigettext.c:722 __GI___dcgettext (domainname=<optimized out>, msgid=<optimized out>, category=category@entry=5) at dcgettext.c:47 Title: nano crashed with SIGSEGV in get_sysdep_segment_value() UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nano/+bug/1710511/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
