Hi All,

I have a latest Webkit Windows build (WebKit-r59711) with Coregraphics/Cfnetwork.
It builds fine.
When I run it using the command debug-safari , then it crashes on launch. Always crashes in WebCore__FontCache__getLastResortFallbackFont().

Seems like its not able to crate a CGFont.
Request to let know If I have missed something with respect to Font.

Crash dump : user.dmp.
