I didn't think it did because if I run  `test/SemaOpenCL/address-spaces-conversions-cl2.0.cl` in `-cl-std=c++` it gives me errors when I initialize a pointer with different AS pointer:

  error: cannot initialize a variable of type '__global int *' with an lvalue of type '__local int *'
  error: assigning to '__global int *' from incompatible type '__local int *'
  error: comparison of distinct pointer types ('__global int *' and '__local int *')

Do you have an example code somewhere?
