ENOENT error for missing file in stack trace

[kevinsawicki]

An ENOENT error is thrown when logging the stack trace for an error that contains a file path that is no longer on disk or fails to be read from disk.

Using CoffeeScript 1.9.1

Steps To Reproduce

• Copy the code below to a file
• Run that file

Code

fs = require 'fs'
path = require 'path'

filePath = path.join(__dirname, 'file.coffee')

# Create a file that exports a function that throws an error
fs.writeFileSync(filePath, "module.exports = -> throw new Error()")

# Require the file
throwsAnError = require(filePath)

# Delete the file
fs.unlinkSync(filePath)

# Call the exported function that throws an error and print the stack trace
try
  throwsAnError()
catch error
  console.error(error.stack)

Expected Output

Error
  at module.exports (/Users/kevin/github/cs-test/file.coffee:1:31)
  at Object.<anonymous> (/Users/kevin/github/cs-test/a.coffee:18:3)
  at Object.<anonymous> (/Users/kevin/github/cs-test/a.coffee:1:1)
  at Module._compile (module.js:456:26)
