1803236 - (layout-crash-memory-corruption) [meta] crashes in layout code that seem likely to really be memory corruption / bad RAM

Status: NEW

(Core :: Layout, task)

Description

[Daniel Holbert [:dholbert]]

Filing this metabug to aggregate layout crashes / crash signatures that we suspect to be partially or entirely explained by memory corruption.

Comment 1

[Daniel Holbert [:dholbert]]

In particular, I'm intending for this bug to covers crashes where we seem to be doing a (largely) read-only walk over the frame tree, and we crash when we traverse some bad data. So: the actual "bad stuff" happened earlier, and we're just now tripping over it when we traverse the frame tree.

("bad stuff" includes bad RAM experiencing a random bit-flip; we have evidence of this being the case in e.g. bug 1300342 comment 5.)

Comment 2

[Gabriele Svelto [:gsvelto]]

Bug 1738651 might be of interest to this effort. Ideally we'd like to be able to identify the majority of these crashes and flag them as suspicious on crash-stats.

(disregard the intermittent failures robot comments here; those were because I mixed up bug 1440376 and this bug when marking a duplicate.)
