Package: weston
Followup-For: Bug #754392

Hi,

I ran weston using valgrind and the logs can be found at:

https://people.debian.org/~bigon/weston_vg.log (warning ~40M)

I'm seeing the following thing (in addition to the mesa leaks):

==13455== Syscall param sendmsg(msg.msg_iov[0]) points to uninitialised byte(s)

==13455==    by 0x4112BB: main (compositor.c:4240)
==13455== 

When the plugin is NOT loaded
(https://people.debian.org/~bigon/weston_vg2.log) less mesa leaks and in
this case I actually see invalid writes.

Cheers,
