In that thread the OP stated he compiled using GCC 4.2, so it wouldn't seem to be an LLVM issue.
I'm not using any blocks (directly) anywhere in this code either. I am making heavy use of Core Animation though…. (possibly nothing to do with the issue). Is there a way to determine which part of my code is linking to this symbol?
I guess I can simply require 10.6 as well as iTunes 10.4, but since (unexpectedly) iTunes 10.4 appears to run under 10.5, it would due nice to support that as well.
