Package: python2.7 Version: 2.7.12-3 Severity: important Hi,
I noticed when running pip to install packages, it always ended with a segfault. The packages get installed but then pip does not quit cleanly. I've attached a backtrace from gdb. I'm around on IRC in #debian-python as irl (also can be found in #debian-devel) and you're welcome to poke me to make me try different things. Thanks, Iain. -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.6.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages python2.7 depends on: ii libpython2.7-stdlib 2.7.12-3 ii mime-support 3.60 ii python2.7-minimal 2.7.12-3 python2.7 recommends no packages.
