Comment:

 This is pretty bad.

 The code [https://cgit.freedesktop.org/gstreamer/gst-plugins-
 base/commit/?id=7b42f26b80acdef7f28bded92e55b1d070286583 was recently
 updated to use ARC] (+ later fixups injecting `-fobjc-arc` where needed).

 Given that the changes are quite invasive, there doesn't seem to be a way
 to revert back to the non-ARC behavior without maintaining a custom
 patchset. We really don't want that.

 Since `gstreamer` is a dependency of `wine` and the 32bit version is
 highly useful, we're in a kind of stalemate situation.

 Replying to [comment:3 ryandesign]:
 > With 1.14.1, it now appears to affect only Mavericks and Yosemite, not
 earlier or later versions.

 I wonder why that is. Did Apple actually implement ARC for x86 in newer
 versions? Why does it seem to work there? Can you find that out?
