Stacktrace from Carbide when S60 emulator crashes

My environment is: Windows XP SP2, 3GB RAM, Qt 4.7 for Symbian, Nokia N97 SDK.

QML document contains a WebView component. When the WebView has either the URL or HTML attributes set, the application crashes. If the WebView component does NOT have either its URL or HTML attributes set, then no crash occurs. Running the application on the Symbian emulator (N97 SDK) the last entry on the callstack was WTF::fastMalloc(). fastMalloc is used by the JavaScriptCore (full stack trace attached). It looks as though there is no memory left and so fastmalloc fails.

I have tried increasing the amount of memory the emulator is launched with but this did not help.Is it anything to do with this webkit bug? http://code.google.com/p/chromium/issues/detail?id=2861

By setting WebView.settings.javascriptEnabled to false, the JavaScriptCore is not used in WebKit, and as a result WebView will load plain html specified in the Webview.html attribute. So it seems it is definitly the use of JavaScriptCore which is causing the problem.

I don't know which version of WebKit is packaged in Qt4.7 binary for Symbian, so cannot provide this information.
