            Bug ID: 159400
           Summary: %TypedArray%.prototype.indexOf is coercing
                    non-integers or non-floats to numbers wrongly
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: ticaiolima at gmail.com

Current implementation of %TypedArray%.prototype.indexOf is coercing the argument to Array type and generating strange results, which are potential bug generators. Check the following example:

>>> new UInt8Array([0, 1, 2]).indexOf("abc");
0

The return value is 0 because "abc" is being converted to 0. It makes more sense of the result is -1.
