Strange Crash from minimization -- even though ng-strict-di is happy. Why? - angularjs

Question

I am seeing a strange crash in the Chrome and Firefox when my code initially loads:
Uncaught TypeError: angular.module(...).constant(...).constant(...).factory(...).factory(...).factory(...).directive(...) is not a function
Next I see a suspicious:
ReferenceError: io is not defined in my socket factory
angular.module("xxx").factory("socket", ...)
when it attempts to access io at the line containing:
var ioSocket = io("", {
path: "/socket.io-client"
})
NOTE: I only see this crash when running a non minimized version of the code.
This project was initially generated by yeoman angular-fullstack. Also I don't believe this second error has anything to do with having something wrong with importing socket.io/socket.io.js -- only an artifact of the first error.
NOTE:
grunt serve
works properly, but
grunt serve:dist
exhibits the crash above.
I originally thought that I had a dependency injection issue and so I turned on the directive ng-strict-di and was able execute grunt serve without any errors. SO this seems to suggest that the failure of grunt serve:dist isn't an injection issue, although I do have many packages being used.
Can you suggest some modifications to the yeoman settings that may help determine what is breaking the code during the build.
grunt serve:dist
basically adds:
concat, uglify, cssmin, and cdnigy
I already have uglify set to not mangle with the option: mangle:false.
I have been fighting with this for three days and I haven't made much progress. If you have any ideas, I would GREATLY appreciate it!
THANKS!
I am running node v4.4.4.

This one was PAINFUL to find. It turns out that the minimization blows up the code IF there is a missing ';' SEMI-COLON at the end of the file with .directive. I found that angular-timezone-selector.js needed to have a ';' added at the end of the file. NOW all works as expected!
I HOPE THIS HELPS SOMEONE ELSE:
Key: check all you bower components that the *.js files end with a ';' where needed.
