Seems to work with development version of CTags.

[David Fishburn]

Works in trunk or next release after 5.8.1

I think the error still persists. Got it with some javascript libraries (e.g. socket.io-client\test\socket.test.js) that I got from npm, but also in minimized files like jquery minimized: http://code.jquery.com/jquery-2.1.4.min.js

I broke down some cases from socket.test.js

0 Warnings:

return { '': function () {} };
return variable = 0;

1 Warning:

return variable = { '': function () {} };

2 Warnings:

(function () {
return module = { '': function () {} };
})();

I checked it with the last ctags version from trunk.

It doesn't reproduced in universal-ctags(https://ctags.io).

[Luke]

CONFIRMED
Didn't know about universal-ctags....

--> Though, there are warnings in some other libraries, see attachment

[Masatake YAMATO]

Thank you for reporting more URLs.
I will try to fix them at https://github.com/universal-ctags/ctags/issues/471 .

[Masatake YAMATO]

Maybe fixed for all the attachements.
