Webkit Windows build with Coregraphics/Cfnetwork crashes on launch in FontCacheWin.cpp.

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.

What version of Safari do you have installed?

Safari Version : 4.0.3(531.9.1)

Hi Adam,

I installed latest version of safari [4.0.5(531.22.7)] on my machine.
Now everything is working fine. I am able to debug as well.

Thank you so much for all the help and support.

Request to let know, what base version of safari is generally required for a windows  build with apple libraries. Also would be interested in knowing as to why it used to crash with 4.0.3 version of safari.

Thanks and hoping for a reply.

Marking resolved per the above comments.

I'm glad it's working again.

We make no attempt to keep WebKit nightly builds working with any but the latest release of Safari. There are periods of time where older releases will still work, but there's never any guarantee. We do this so that WebKit's code doesn't become filled with hard-to-maintain and hard-to-test backward-compatibility code.
