[pkg-lxc-devel] Bug#837743: lxc: Segfault (symbol size mismatch) when starting container created with "download" template

[Michael Gardner]

Package: lxc
Version: 1:2.0.4-1
Severity: important

I created an unpriviliged Ubuntu (xenial, amd64) container using "lxc-create -n foo -t download", and it seemed to complete with no problems. But when I try to start this container using "lxc-start -n foo", I get this error:

>lxc-start: Symbol `ns_info' has different size in shared object, consider re-linking
>Segmentation fault

Lxc doesn't provide any more logging information or output, even when I set --logpriority to something high. I also tried creating a Debian (sid, amd64) container using the download template and got the same error.
