           Summary: Assertion failure in MemoryCache::removeFromLRUList
                    when running fast/tokenizer/001.html
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Keywords: LayoutTestFailure, NeedsRadar
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: aroben at apple.com


To reproduce:

1. run-webkit-tests fast/tokenizer/001.html

You'll hit an assertion in MemoryCache::removeFromLRUList:

    ASSERT(found);

It looks like this test tries to load nonexistent.js, which fails (surprise!). When it fails, we try to remove it from the MemoryCache, but of course it isn't in the cache to begin with.

Here's the backtrace:
