An error message

ELinks produces several error messages in a row stating "(void 0) is not a function" on right after opening any URL or clicking any link (see screenshot attached). Turning ECMAScript itself off or adding 'set ecmascript.error_reporting = 0' into ~/.elinks/elinks.conf changes nothing.

Version-Release number of selected component (if applicable): elinks-0.12-0.51.pre6.fc26.x86_64, js-1.8.5-27.fc26.x86_64

How reproducible: always

Steps to Reproduce:
elinks http:/fedoraproject.org
or, say, elinks /etc/hosts
or elinks whateveryouwant

Actual results: the abovementioned error

Expected results: the actual contents
Comment 1 Kamil Dudka 2017-04-28 10:54:10 UTC 
Confirmed.  I can reproduce it on f26 and rawhide but not on f25.  ELinks code has not changed since f23.  So I suspect this is caused by a change elsewhere.

A possible solution would be to disable JavaScript completely.  We have been debugging bugs like this recently despite most ELinks' users do not use the feature.  To be honest, I am not aware of any web site where one could take an advantage of the JavaScript support in ELinks.

Let me poll fedora-devel to see whether we still have any ELinks/JavaScript users out there before I try to debug it further.

Replying here since I'm not subscribed to the list yet: actually, I (occasionally) use JS in ELinks and would be happy to help with testing it. Currently there's a bunch of mozjs* packages in Fedora and I'm trying to build/run elinks against those. Will report in here as soon as I get some actual result.
Comment 4 Kamil Dudka 2017-05-02 16:39:45 UTC 
This bug is caused by the following patch:

https://src.fedoraproject.org/cgit/rpms/js.git/tree/mozjs1.8.5-tag.patch?id=a2f53826

Just rebuilding elinks seems to fix it.

I am also able to read e-mails in GMail but it redirected me to the basic HTML version because my browser was not supported.

Not that I have any account there, but those pages load fine in my ELinks.
