[Bug 753147] Pitch element causes pipeline failures and crashes when used with autoaudiosink

Sat Aug 1 17:14:14 PDT 2015

https://bugzilla.gnome.org/show_bug.cgi?id=753147

--- Comment #1 from Sjors Gielen <gnome-bugzilla at sjor.sg> ---
A slightly simpler command using only plugins from base and good, except for
pitch, and still triggers ASAN, is the following. When repeated, this triggers
different kinds of ASAN errors similar to the ones seen earlier, increasing my
suspicion of a race condition.
