            Bug ID: 188489
           Summary: Unary - applied to a variable causes an exception in
                    ConstexprFolder
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGPU
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mmaxfield at apple.com

visitCallExpression() in ConstexprFolder calls unifyNode() on the argument, which can be a variableRef, which asks the "variable" parameter what its unifyNode() is, but it hasn't been set because we are doing this before the NameResolver or Checker has run.
