'src=' anywhere inside JavaScript causes Internal Server Error 500

[Regaddi]

Whenever I use 'src=' anywhere inside a string in JavaScript, the generated .js file gets an Internal Server Error 500 containing the following message:

/*
[exception] 500 | Internal Server Error | ErrorException
[message] Notice: Uninitialized string offset: 0 in /Volumes/Namics/sew-eurodrive/vendor/brunschgi/terrific-core-bundle/Terrific/CoreBundle/Filter/TerrificRewriteFilter.php line 64

This is produced with a console.log('src=')or $('<img src="/some/image/path" />') anywhere inside a Terrific module in the project.
