1267647 - crash in RegisterStaticAtoms due to bad hardware (disk? memory?)

Status: RESOLVED WONTFIX

(Core :: XPCOM, defect)

Description

[Calixte Denizet (:calixte)]

This bug was filed from the Socorro interface and is 
report bp-023ebcb2-cc34-4c83-b378-e113e2160426.
=============================================================

It's a startup crash and it just appeared the 2016-04-25 on aurora.

Comment 1

[David Baron :dbaron:]

There have been a few spikes, from a single user, on both aurora and nightly.

I looked at bp-b9973864-024d-401d-8398-9e30b2160429.  Essentially we're crashing inside HashString(), allegedly 0x1917FC characters into the string, and with 0x403fc4a8 left to go.  We crash when we cross a page boundary.  (The crash addresses on x86, where crash addresses are reliable, all end in three zeros.)  The actual string should be "itemref", which is 7 characters.

This makes me suspect disk corruption of the binary.

(Each spike from a single user, not necessarily the same for the different spikes.)

Comment 3

[David Baron :dbaron:]

bp-286bc19f-dd8d-4905-b324-3b6932160407, from the same user, 7 seconds earlier, has a crash that looks like a bit flip (RBX == 0x200007fec6900028), where the 2 in the high bit seems wrong.  That makes it seem more like bad memory, which could also explain the other.

[Nicholas Nethercote [inactive]]

Indeed, this one is just iterating over static data. There's no obvious possibility for error without some kind of problem beyond our control, such as disk corruption or hardware faults.

[Julien Cristau [:jcristau]]

Too late for firefox 52, mass-wontfix.

Comment 10

[Nathan Froyd [:froydnj]]

Is this even worth keeping open if we know/suspect we can't fix it per comment 4?

Comment 11

[David Baron :dbaron:]

I tend to think it's better to keep it open, given that we don't have a better mechanism for tracking crashes that we can't fix, and an open bug is a sign that it's not fixed.

Closing because no crashes reported for 12 weeks.
