Description:
When my project closes an OpenAL device, ASAN reports an error. This wasn't the case a couple of days ago.

Additional info:
* package version(s)
* config and/or log files etc.

ASAN report:

Can't really tell since when this problem exists.

Anything I can do to help?

When clang 3.5 is available, please retest.

clang 3.5 is available, but I haven't had the time to try it yet.

Can confirm this is fixed.
