Do you have Safari 3.2.1 installed, or some earlier version?

[Franck]

I have the same problem on Vista, with Safari 3.2.1 installed

A call to CFURLCopySharedURLCache was added in <http://trac.webkit.org/changeset/38010>.

[Jyrki Wahlstedt]

I checked, seems to be 3.2.1

The problem here is that the nightly build was done on a machine with the new CFNetwork headers. If you did your own build on a machine that had the old CFNetwork headers it would work fine. To make this work on either version I can change this into a runtime check instead of a compile-time check. Or we can build nightly builds on a machine with the old public CFNetwork headers.

Is there any reasonable way for us to make this work with Debug_Internal configuration?

I only recently became aware of this issue.

Since GetModuleHandle only will return modules that are already loaded, we can unconditionally look for both CFNetwork_Debug and CFNetwork and use the first one we find. I think we should change all call sites that are using GetModuleHandle to find CFNetwork to do this.
