Crash in FixMath and MachineExceptions.h after adding AudioToolbox.framework

Made a new window application. Right-clicked Frameworks > Add Existing Frameworks. Selected Frameworks folder, then AudioToolbox.framework. Build, and 11 crashes.

#elif defined __ppc__ || __开发者_运维问答ppc64__

#define _IntSaturate(x) ((int) (x))

#else

#error "Unknown architecture."
// To use unoptimized standard C code, remove above line.
#define _IntSaturate(x) ((x) <= -0x1p31f ? (int) -0x80000000 : \
    0x1p31f <= (x) ? (int) 0x7fffffff : (int) (x))

#endif

Tried commenting that line, then MachineExceptions still crashes:

typedef CALLBACK_API_C( OSStatus , ExceptionHandlerProcPtr )(ExceptionInformation * theException);

error: expected ")" before '*' token

..what the hell happened? I'm 99.9% sure I've never modified the AudioToolbox or any other framework.

Just scrapped the project, copied main classes and everything working smoothly again.
