            Bug ID: 252344
           Summary: [Win] Windows port needs to fix FIXME in
                    WTF::Config::permanentlyFreeze() in JSCConfig.cpp
           Product: WebKit
           Version: WebKit Local Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

Currently, we don’t mprotect the JSC::Config for the Windows port yet.  We believe Windows has a VirtualProtect API that can be used to do this.

#elif OS(WINDOWS)
    // FIXME: Implement equivalent, maybe with VirtualProtect.
    // Also need to fix WebKitTestRunner.

    // Note: the Windows port also currently does not support a unified Config
    // record, which is needed for the current form of the freezing feature to
    // work. See comments in PlatformEnable.h for UNIFIED_AND_FREEZABLE_CONFIG_RECORD.
