             Bug #: 11644
           Summary: clang should throw std::bad_array_new_length when the
                    allocation size for new overflows
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++0x
        AssignedTo: unassignedclangbugs at nondot.org

C++11 has a new exception type: std::bad_array_new_length.  And per the
standard, "If the value of that expression is less than zero or such that the
size of the allocated object would exceed the implementation-defined limit, no
storage is obtained and the new-expression terminates by throwing an exception
of a type that would match a handler (15.3) of type std::bad_array_new_length".
 Our current behavior is likely good enough in most cases, but it isn't
strictly compliant.
