Just to be clear: this is a bug in DumpRenderTree, not WebKit. fast/forms/input-text-paste-maxlength.html triggers this same crash. and fast/text/atsui-bidi-control.html fast/forms/focus-control-to-page.html just crashed in a Release build: http://build.webkit.org/results/Windows%207%20Release%20(Tests)/r79821%20(9819)/fast/forms/focus-control-to-page-crash-log.txt Created attachment 83992 [details]
Use iswalpha instead of isalpha when dealing with wchar_ts in EditingDelegate

Use iswalpha instead of isalpha when dealing with wchar_ts in EditingDelegate
Wow. Can't the compiler help us with this? I guess win32 is al C and thus compilers do nothing...

To reproduce: 1. gflags /p /enable dumprendertree.exe /full 2. run-webkit-tests fast/forms/input-text-maxlength.html You'll crash inside isalpha beneath EditingDelegate::checkSpellingOfString. Looks like we're passing a non-ASCII character to isalpha, which isn't allowed.
