I was getting a stack overflow error when trying to minify a CSS file. Updating to 2.4.7 seems to have fixed it.
Might want to test to see if there are any regressions first. I haven't found any.
update yuicompressor to 2.4.7
The node version (uglifyjs + cleancss) works better; might be worth switching over. Either way, I'll pull in the change :)
I assume that's what our servers are using, since it's not throwing the error. I'll switch over then!
