CLI: Line numbers shown as NaN in stack trace when compiling CoffeeScript inside CoffeeScript

[wastl-junior]

When calling the following script lineNumbers.coffee:

cs = require 'coffee-script'
cs.compile ""

throw new Error "Some Error"

using coffee lineNumbers.coffee
I get the following stacktrace:

Error: Some Error
    at Object.<anonymous> (F:\test\lineNumbers.coffee:NaN:NaN)
    at Object.<anonymous> (F:\test\lineNumbers.coffee:NaN:NaN)
    at Module._compile (module.js:NaN:NaN)
    at Object.exports.run (F:\test\node_modules\coffee-script\lib\coffee-script\coffee-script.js:NaN:NaN)
    at compileScript (F:\test\node_modules\coffee-script\lib\coffee-script\command.js:NaN:NaN)
    at compilePath (F:\test\node_modules\coffee-script\lib\coffee-script\command.js:NaN:NaN)

    at run (bootstrap_node.js:NaN:NaN)
    at startup (bootstrap_node.js:NaN:NaN)
    at bootstrap_node.js:NaN:NaN

When commenting the compile call out:

cs = require 'coffee-script_1_12_1_works'
#cs.compile ""

throw new Error "Some Error"

I get a reasonable line numbers:

Error: Some Error
    at Object.<anonymous> (F:\test\lineNumbers.coffee:4:7)
    at Object.<anonymous> (F:\test\lineNumbers.coffee:1:1)
    at Module._compile (module.js:571:32)

    at Object.<anonymous> (C:\Users\Administrator\AppData\Roaming\npm\node_modules\coffee-script\bin\coffee:15:45)
    at Module._compile (module.js:571:32)

    at startup (bootstrap_node.js:151:9)
    at bootstrap_node.js:542:3

This occurs using coffee-script 1.12.6. This behaviour is new, everything works correctly using coffee-script 1.12.1 and below. I also get proper line numbers using the newest coffeescript version when I execute the file using node -r coffee-script/register lineNumbers.coffee

Can you narrow down when this broke?

The coffee command is intended primarily for compiling and debugging, and is not as full featured as running via Node.

it seems to be related to this pull request #4428

the problem is, that sourceMaps['< anonymous >'] is defined by running coffee and then is always returned for any file:
https://github.com/jashkenas/coffeescript/blob/master/src/coffee-script.coffee#L363

quick workarounds would be to set options.filename to anything but anonymous or to set options.sourceMap to false

Fixed by #4645.
