Why?
I'm using visual studio 2005, configurations is RelWithDebInfo.

Usually the content of a WTF::String should be stored in the m_data8 (Latin1) or m_data16 (UTF16). From my personal experience I can say that RelWithDebInfo never worked. So if I wanted to Debug code I turned off the optimizations for the files I wanted to Debug, but not for all since then the binary was to big to start.

You can use the printf to check the log information.

I haven’t tried this yet myself but have bookmarked this:

 

http://www.chromium.org/developers/how-tos/how-to-set-up-visual-studio-debugger-visualizers#TOC-WebKit-specific-visualizers

 

Note that WTF::String used to live in the WebCore namespace, so you’ll have to tweak that.
