Bug 43557 – REGRESSION: Unable to open gmail messages (unshift broken?)

• Component: JavaScriptCore
• Status: RESOLVED FIXED

[John Moe]

1. Go to gmail.
2. Click on a message.
Nothing happens.

Is this related to Bug 43314?  It worked in nightlies before the crashing began and has not worked since the crashing was fixed.

This error is logged:
TypeError: Result of expression 'b.b[e]' [undefined] is not an object.   line 124

line 124:
function jha(b,a){for(var c=[a],d=jd(b.b[a].P4);d.length;){var e=d.pop();if(!b.b[e].nd()){c.unshift(e);Array.prototype.unshift.apply(d,b.b[e].P4)}}md(c);return c}function kha(b){if(b.B==b.Q){b.B=j;b.Q.DL(v(b.xa,b))}}function bi(b,a){b.b[a].DL(v(b.xa,b));ed(b.D,a);ed(b.h,a);b.h.length==0&&lha(b);ai(b)}function ci(b,a){b.Z=j;b.B=b.b[a]}function di(b,a){!b.B||a!=b.B.Fa();b.B=j}

I actually believe that this issue is related to https://bugs.webkit.org/show_bug.cgi?id=43401 which has been fixed and landed.

I can surely confirm this bug which forced me to revert to Safari (5.0.1) from WebKit nightly. It started to happen about a week ago.

JS console shows exactly the same error as mentioned above.

Should be fixed in https://bugs.webkit.org/show_bug.cgi?id=43401 , landed in r63470.
Please reopen this bug is issue persists in nightly after this revision.

[Shamil Kerimov]

are you sure that it was landed in r63470 and not in r64773? using r64727 and still having this issue.

[Gavin Barraclough]

My bad, yep, meant to say should be fixed in r64773.
