@swift-ci create

loganwright (JIRA User) i used SwiftSyntax to visit the given code example as such

import Foundation
 import SwiftSyntax

let input = URL(fileURLWithPath: "/tmp/test.swift")
 let result = try! SyntaxTreeParser.parse(input)

class Visitor: SyntaxVisitor {
   override open func visit(_ node: PoundFileExprSyntax)

{     print("visited")   }

}

Visitor().visit(result)

This code executes successfully without hitting a `bus 10` error.

Could you also share the code example you were using to visit the crashing case?

This no longer reproduces with the new parser or the old SwiftSyntaxParser. Please verify this against a recent checkout of swift-syntax.
