            Bug ID: 191063
           Summary: Static global 'fastHandlerInstalled' conditionally
                    declared in WasmFaultSignalHandler.cpp
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jmason at ibinx.com

The static global variable 'fastHandlerInstalled' is declared inside an #if block in WasmFaultSignalHandler.cpp, but referenced later outside it.  This results in a compilation error when the #if condition is not met.

In this specific case, the combination of conditions which result in the error are ENABLE(WEBASSEMBLY) and !ENABLE(WEBASSEMBLY_FAST_MEMORY).

Rescoping the declaration outside the #if block resolves the problem.
