Package: ubuntu-dev-tools Version: 0.155 Severity: important Hi,
I use cowbuilder-dist as a frontend to qemu-user-static, to track down a build failure on mips. the commands I used are: export UBUNTUTOOLS_DEBIAN_MIRROR=http://10.x.x.x:3142/debian (Note: this is my local apt-cacher-ng. If I specify it by name, debootstrap fails to resolve the DNS name, but if I give the IP it works. Not sure if this is misconfiguration on my side.) cowbuilder-dist sid mips create --main-only But if I try to build dspdfviewer using the "build" command it fails when trying to set up the dependencies. dget http://http.debian.net/debian/pool/main/d/dspdfviewer/dspdfviewer_1.14-2.dsc cowbuilder-dist sid mips build dspdfviewer_1.14-2.dsc (normal output snipped, the last few lines are) Need to get 35.0 MB/120 MB of archives. After unpacking 550 MB will be used.

Note that the problem is not specific to dspdfviewer as a package-to-be-built, I get the same segfault when trying to build vim, or even the hello package, which should have a really small dependency list. Known workaround: cowbuilder-dist sid mips login --bindmounts /dir/to/source apt install devscripts equivs cd /dir/to/source mk-build-deps -ir debuild -b -uc -us In case I filed this against the wrong package, please redirect accordingly. I'm not sure which component actually triggers the segfault. Thank you, - Danny PS: In case the problem is not reproducible on your machine, please tell me how to save the core dump from the segmentation fault. I can't find it in my ~/pbuilder folder, and I assume it got auto-deleted. -- System Information: Debian Release: stretch/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 4.4.0-1-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages ubuntu-dev-tools depends on: ii binutils 2.26-5 ii dctrl-tools 2.24-2 ii devscripts 2.16.1 ii diffstat 1.61-1 ii distro-info 0.14 ii dpkg-dev 1.18.4 ii lsb-release 9.20160110 ii perl 5.22.1-7 ii python 2.7.11-1 ii python-apt 1.1.0~beta1 ii python-debian 0.1.27 ii python-distro-info 0.14 ii python-httplib2 0.9.1+dfsg-1 ii python-launchpadlib 1.10.3-3 ii python-lazr.restfulclient 0.13.4-5 ii python-ubuntutools 0.155 pn python:any <none> ii sudo 1.8.15-1.1 Versions of packages ubuntu-dev-tools recommends: ii bzr 2.7.0-2 ii bzr-builddeb 2.8.9 ii ca-certificates 20160104 ii cowdancer 0.78 ii debian-archive-keyring 2014.3 ii debian-keyring 2016.01.20 ii debootstrap 1.0.79 ii dput 0.9.6.4 ii genisoimage 9:1.1.11-3 ii libwww-perl 6.15-1 ii lintian 2.5.41 ii patch 2.7.5-1 ii pbuilder 0.223 ii python-dns 2.3.6-3 ii python-soappy 0.12.22-1 ii quilt 0.63-3 ii reportbug 6.6.6 Versions of packages ubuntu-dev-tools suggests: ii python 2.7.11-1 ii python-simplejson 3.8.1-1 ii qemu-user-static 1:2.5+dfsg-5 -- no debconf information
