This is actually <rdar://problem/10670574>, reported from http://code.google.com/p/angleproject/issues/detail?id=277

We can put in a temporary workaround by using built-in function translation when running on Intel. Then, when the fix is made to the Intel driver on OS X, we can remove the workaround.
