            Bug ID: 148439
           Summary: cryptographicallyRandomValuesFromOS should use
                    CCRandomCopyBytes when available.
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

Recently, we switched to using arc4random_buf on Darwin but further research indicates that arc4random_buf has the same behavior we had before and thus we were just pushing the problem further down the stack. CCRandomCopyBytes, however, appears to be more advanced and has much better error handling than we had before. Additionally, to make any future debugging easier I added a CRASH_WITH_MESSAGE to Assertions that adds a debug trace to crash logs with the CCRandomCopyBytes error message.
