Problem with javascript compression on my regex

[hug0]

Hi,
composer :
"ceesvanegmond/minify": "2.0.*",
On :
Laravel 4.2

I got an error when i compress my javascript.
In my js code i got :

/(NaN| {2}|^$)/.test(a)

After compressed :

/(NaN|{2}|^$)/.test(a)

Obviously, an error occured ! How can i edit the javascript compression class to correct my situation ?

Thx a lot !
