Hi, thanks for emailing; I don't get bugzilla notifications, so I hadn't seen this yet. > It’d be great, if you took a look, and advised if this commit (and > follow-ups) should be reverted, until the issue is analyzed. There have been a number of fixes to that commit (which I see are mentioned in a quick skim of the bug), but they've mostly been around additional slab debugging features. If it's causing a problem outside of that, my instinct would be there might be a use-after-free happening, but I'll go read the bug more closely now, and comment there (or here, if needed).
