I have python-2.7.1-r1 and python-3.1.3-r1. The bug only happens when I try to print something. For example :python x = 0 works. Even if I compile both python and vim with USE="debug" and launch vim from gdb I don't get a stack trace or a core file. There are no debugging symbols in libpython2.7.so which means I can only see the assembly instructions. If I set a breakpoint to _Py_Print I can stop before the crash. Reproducible: Always Steps to Reproduce: 1. emerge vim 2. vim 3. :python print "hello world" Actual Results: Vim crashes with the following message: *** stack smashing detected ***: vim - terminated vim: stack smashing attack in function <unknown> - terminated Report to http://bugs.gentoo.org/ In the syslog I see: 2011-03-02T20:17:28+01:00 user notice ***[]: stack smashing detected ***: vim - terminated 2011-03-02T20:17:28+01:00 user notice vim[]: stack smashing attack in function <unknown> - terminated 2011-03-02T20:17:28+01:00 user notice Report[]: to http://bugs.gentoo.org/ Expected Results: It should display "hello world".
Please paste your `emerge --info app-editors/vim' output in a comment.

Can't reproduce it, but here goes.
(In reply to comment #3) > Can't reproduce it, but here goes. > I created a small chroot environment in which I can reproduce the crash. You need to bind-mount /dev and mount proc. You can start it with chroot /path/to/vim-7.3.102-crash /usr/bin/vim. It looks ugly for some reason but still crashes when I type :python print. I uploaded it here: http://www.megaupload.com/?d=5MTV1I7V . I'm really very sorry for the annoying hosting but it's 22MB so I can't post it here. The SHA256 should be 78e4eb888c2b96e439f3d57d7a7b01d854858b7d5e10231114096a7ba5550e68 . It's understandable if you don't want to run some binary from the internet. In that case I would try to debug it myself but I can't get debugging symbols for libpython2.7.so and it looks really hopeless that way. If you can tell me how to get a stack trace or core dump in cases like this that would also help a lot.
A newer version of vim has been released, and some of the patches include fixes for the python support. Can you please try upgrading to 7.3.162 (just added to the tree today) and see if you still have the same issue?
It still happens with 7.3.162.
And it still happens with 7.3.189
Doesn't seem to be an issue anymore in recent versions.
