I can confirm that this is still a problem On Windows 7 VS2012 Release build.

It appears that atomicCanonicalTextEncodingName is executing when an access violation occurs, due to deref'ing a null pointer. Several related 'this' pointers have become null. 

The code is difficult to debug with /O2 optimizations, as lots of code is relocated, particularly mutex locking. So I built with /O1 and lo-and-behold no access violations. I also tried /Ox which but this gives the same result as /O2.

So a workaround is to compile WebCore with /O1 optimization flag.
