Upstreamed - https://bugs.webkit.org/show_bug.cgi?id=77270 looks to have regressed in https://trac.webkit.org/changeset/105005/
,

I think the regression range is wrong here. It shows as regressing 3 weeks ago, but is crashing on m17 beta.
,
Jan 30 2012
there is almost 0% chance that the regression range is wrong since we now compare the crash stacks, and when i clicked redo, it still came up with same range. Also, i am quite confident that it is mitz's font change did it. Marty, can you try check the repro against asan latest beta and see if it still crashes. it shouldn't be in m17 unless someone merged it to m17 branch. Branched Chromium at revision 113143 Branched Webkit at revision 101876 Marty, this might be a problem in an intermediate faulty build that cause the repro to not crash there, or might need a higher timeout for the repro. can you try this locally and see what might be going wrong.

This does seem to be reproducing with the same stack in the latest m17 asan beta. I'll try to see what might be going on with the regression range now.

Ryosuke has a generic patch upstream. This should cover areas other than svg as well. Really like the approach.
