http://clang.llvm.org/docs/ObjectiveCLiterals.html#id4 tells you:

"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."

As Alexey pointed out, WebKit still supports the legacy runtime for 32-bit Mac applications. Any code that compiles in that configuration cannot use modern runtime features.
