I can't think of a plausible scenario in which changing the compiler
version would affect the default parameters of an audio unit on an
already-deployed OS.
More likely, something about clang's code generation has changed.
Usually when that has an adverse effect on your code, it means that your
code had a hidden bug that is now being exposed, though bugs in clang's
ARM floating-point codegen are certainly not unheard of.
Long shot: are you testing this on 64-bit hardware (ARMv7s)? Does the
problem go away if you build 32-bit only? If this alleviates the issue,
perhaps switching to Xcode 6 enabled 64-bit codegen when it was not
previously enabled.
