UglifyJS 3.1.7 minifies incorrectly 3.1.6 works

[Havunen]

Hey

After upgrading to 3.1.7 from version 3.1.6 our minified output is incorrect. 3.1.6 is working as expected.

The output build is so much different that I don't see any point pasting it here (2.2MB) :( ...
The most visible issue occurs with inline styles that are set using this.element.style.margin ="example";

3.1.7 broke our production setup. I am getting

ERROR in commons.js from UglifyJs

Nothing changed expect for the version upgrade from 3.1.6 to 3.1.7.

Closing as duplicate.

This is actually still broken in 3.1.8, I'm not seeing this maximum callstack error, but minified code is incorrect. I will try to create reduced test case this weekend.

[Havunen]

3.1.9 seems to have fixed the issue. 👍
