           Summary: TypedArray should throw exception if length not a
                    multiple of element size
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P3
         Component: WebGL
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: enne at google.com


>From the Typed Array spec: "If length is not explicitly specified, the length of the ArrayBuffer minus the byteOffset must be a multiple of the element size of the specific type, or an exception is raised."

Therefore, this code should throw an exception, but currently doesn't:

var buffer = new ArrayBuffer(1);
var buf = new Uint16Array(buffer);

Once fixed, this test case should be added to the Khronos array-unit-tests.html conformance test.
