This is a known issue that was recently solved on OS X. Declaration of NSAssert macros in (Obj-)C++ mode are broken (they don't use the vararg macro syntax that is supported by recent c++ compiler).
I didn't tried on iOS, but I suspect this is the very same issue that is not yet fixed in the SDK you are using.
