Huge amount of comments causes RangeError: Maximum call stack size exceeded

[Suunto-PekkaV]

A 10 000 line comment at http://lisperator.net/uglifyjs/#demo causes RangeError: Maximum call stack size exceeded -error.

Attached is the input that should reproduce this error. The file has simply // Your code goes here -line 10 000 times.

For my sanity: did you encounter this in a real-world scenario?

This is caused by recursive calls from next_token → handle_slash → skip_line_comment → next_token.

[Suunto-PekkaV]

It happened in a real world case where large chunk of json data was commented out.

If you're running it manually, you can work around by doing something like node --stack-size=100000 bin/uglify your-file-here.js.

Fixing this completely requires rewriting chunks of the parser, which may take some time.

I'm also encountering this error with a file that is 135,594 lines long (a nasty, huge bundle of our 3rd party dependencies).
