The issue

When I compiled a C source code directly into a Wasm binary using clang, a-Shell crashed in a destructor of PrettyStackTraceEntry.

Specifically, the following line's assert fails after it is called some times.

	import Logging

	LoggingSystem.bootstrap { label in
	var handler = PlaygroundHandler(label: label)
	handler.logLevel = .trace
	return handler
	}

	let logger = Logger(label: "hoge")

	extension Result {
	func expect(_ message: String) -> Success {
	switch self {
	case let .success(value):
	return value
	case let .failure(error):
	preconditionFailure("\(message): \(error.localizedDescription)")
	}
	}

	extension Optional {
	func expect(_ message: String) -> Wrapped {
	guard let value = self else {
	preconditionFailure(message)
	}
	return value
	}
	}

	import XMLCoder

	struct Root: Equatable {
	let elements: [Choice]
	let name: String
	let description: String?
	}

	extension Root: Codable {
	enum CodingKeys: String, CodingKey {

	import PlaygroundSupport
	import SwiftUI

	final class ContentViewModel {
	@Published var text = ""
	}

	extension ContentViewModel: ObservableObject {}

	struct ContentView {

	#!/bin/bash

	set -e

	modprobe libcomposite
	cd /sys/kernel/config/usb_gadget/
