crash in mozilla::Scroll
Frame Helper::Scroll To Impl(ns Point, ns Rect const&, ns IAtom*)
This bug was filed from the Socorro interface and is report bp-aa847442-e4dc-4fe5-a276-68abd2140311. ============================================================= One way to hit this is: * start editing a wiki.m.o page * use cmd-f to search for a word * click the 'Show preview' button, or 'Page' in the header * search again with cmd-g (nothing happens) * search again with cmd-g (crashes) More crash reports: bp-30c48d6f-c897-4a81-917c-92cb52140311 bp-b624898f-b8fc-4215-bcab-4a0712140311 bp-5a7d8cc7-51c9-47c6-9ba9-79ea12140311 bp-040f652d-cc0a-48ba-9754-20c042140311 bp-467c2a07-193c-40d3-bef0-3de852140311
I'm using Nightly on mac, crashing in todays and yesterdays builds, no information about further back.
Could you provide more specific instructions? (a specific wiki page to edit & specific word to search for) I just tried to reproduce with https://wiki.mozilla.org/index.php?title=Platform&action=edit and the word "vidyo" (which occurs once on the page), and I didn't crash. (using latest Linux nightly, datestamp 2014-3-11)
I can't reproduce on that page, but this works: 1, load https://wiki.mozilla.org/index.php?title=Releases/Firefox_28.0/BuildNotes&action=edit 2, cmd-f to search for mock 3, click on 'Page' to switch back to actual page 4, cmd-g once to crash Or use the 'Show Preview' button at 3 and cmd-g twice to crash. Reloading with cmd-r at 3 doesn't crash.
With the STR in comment 3 I'm crashing on this line (on Linux): http://hg.mozilla.org/mozilla-central/annotate/69fbe69ddb8c/layout/generic/nsGfxScrollFrame.cpp#l2089 which was added Feb 28, 2014 in bug 968647 part 1 (so I'm guessing it's a regression from that bug).
docshell seems to be null

Comment on attachment 8392072 [details] [diff] [review] fix w/ test This is regression by bug 968647. Type ahead find seems to cache old pres shell, so docshell is null. Since any 3rd party addon may cache pres shell, I add null check in ScrollToImpl for more safety.

Comment on attachment 8392072 [details] [diff] [review] fix w/ test [Approval Request Comment] Bug caused by (feature/regressing bug #): bug 968647 User impact if declined: When user uses find menu, Firefox may crash after navigating to other page. Testing completed (on m-c, etc.): landed in m-c. And test case is comment #0. Also, I added mochitest for this. Risk to taking this patch (and alternatives if risky): Added nullptr check only. So low risk. String or IDL/UUID changes made by this patch: No

Why does this test need Timer.jsm, exactly? That causes it to try to clobber the default setTimeout/clearTimeout on the global...
(In reply to Boris Zbarsky [:bz] from comment #14) > Why does this test need Timer.jsm, exactly? That causes it to try to > clobber the default setTimeout/clearTimeout on the global... Because I need timer. Ah, I will change it to Components.utils.import("resource://gre/modules/Timer.jsm", xxxx);
> Because I need timer. the test runs in a window. So it has timers already...
