I'm running qemu-arm version 4.2.1 (Debian 1:4.2-3ubuntu6.17) on Ubuntu 20.04.03, but I seem to still be affected by this (or something very much like it). In my case it is armhf exim4 crashing while creating a chroot on an amd64 host. The final command run from deeply within exim4's postinst is:
/usr/sbin/exim4 -C /var/lib/exim4/config.autogenerated.tmp -bV and produces Exim version 4.93 #5 built 28-Apr-2021 13:19:17 Copyright (c) University of Cambridge, 1995 - 2018 (c) The Exim Maintainers and contributors in ACKNOWLEDGMENTS file, 2007 - 2018 Berkeley DB: Berkeley DB 5.3.28: (September 9, 2013) Support for: crypteq iconv() IPv6 GnuTLS move_frozen_messages DANE DKIM DNSSEC Event I18N OCSP PRDR SOCKS TCP_Fast_Open Lookups (built-in): lsearch wildlsearch nwildlsearch iplsearch cdb dbm dbmjz dbmnz dnsdb dsearch nis nis0 passwd Authenticators: cram_md5 plaintext Routers: accept dnslookup ipliteral manualroute queryprogram redirect Transports: appendfile/maildir/mailstore autoreply lmtp pipe smtp Fixed never_users: 0 Configure owner: 0:0 Size of off_t: 8 qemu: uncaught target signal 11 (Segmentation fault) - core dumped Segmentation fault (core dumped) Interestingly, even /usr/sbin/exim4 -C /dev/null -bV produces the same result, so it likely doesn't depend on any configuration at my end and should be reproducible. Please let me know if there is anything I can do to help debug further. Should I create a separate ticket? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1749393 Title: sbrk() not working under qemu-user with a PIE-compiled binary?
