           Summary: ASSERT_WITH_SECURITY_IMPLICATION should crash in a
                    distinct way
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ayao at apple.com


ASSERT_WITH_SECURITY_IMPLICATION currently calls CRASH().  There are many other non security related code paths that call CRASH().  ASSERT_WITH_SECURITY_IMPLICATION should crash in a distinct way in order to help screen fuzzing bugs.

The attached patch adds a CRASH_WITH_SECURITY_IMPLICATION which is the same as CRASH except it accesses 0xfbadbeef instead of 0xbbadbeef. 

The same as before, in release builds, ASSERT_WITH_SECURITY_IMPLICATION will do nothing unless it was built with ASAN, which required moving the code around a little, since before it just called ASSERT() when ASAN was not defined.
