<pre>TestWebKitAPI crashed in TestWebKitAPI: TestWebKitAPI::SharedBufferTest_copyBufferCreatedWithContentsOfExistingFile_Test::TestBody with ASan enabled.
The bug is that strnstr() assumes the second argument is null-terminated, and the implementation of strnstr() on OS X calls strlen() on the second argument. This causes an out-of-bounds read if the memory after the second argument doesn't happen to contain a NULL character.</pre>
