Comment (by Ionic):

 No, it looks like the Object Subscripting fails. I've added support for
 this manually and made sure that `clang-3.4` supports it. I see you're
 building on i386. Looks like Object Subscripting doesn't work on i386 at
 all.

 From
 http://releases.llvm.org/3.4/tools/clang/docs/ObjectiveCLiterals.html:
 > An Objective-C subscript expression occurs when the base operand of the
 C subscript operator has an Objective-C object pointer type. Since this
 potentially collides with pointer arithmetic on the value, these
 expressions are only supported under the modern Objective-C runtime, which
 categorically forbids such arithmetic.

 This "modern Objective-C runtime" is only available on x86_64 - as a
 compiler feature.

 I'm afraid there isn't much I can do about that. I could probably patch
 mpv's source code to not use Object Subscripting at all, but that's
 probably a lot of work.
