Proper handling of large mark stack insertion
I noticed that for the FOTN the large markstack gets pretty full.

Wait, this seems like a serious bug to me. Is there any guarantee that the assertion will succeed? If push returns false, we should probably just do the normal thing and not use the large object path. Thanks for finding this!
Yeah I wanted to ask you why we don't check the return value there. I will come up with another patch.
Summary: Add success assertion for large mark stack insertion → Proper handling of large mark stack insertion

Comment on attachment 528863 [details] [diff] [review] patch Thanks. Another way to do it is like this: if (...is large dense array... && gcmarker->largeStack.push(LargeMarkItem(obj))) /* do thing, push succeeded */; else clasp->trace(gcmarker, obj); I'm not sure if this is better or worse, but it avoids code duplication.

Yeah I was thinking of the same code but I have never seen it in SM so I didn't want to start with it :)

Do we need this fix on Aurora or Beta?
(In reply to comment #9) > Do we need this fix on Aurora or Beta? Depends if bug 616666 is in there.
Bill is the explicit mark stack on Aurora?
(In reply to comment #12) > Bill is the explicit mark stack on Aurora? It seems like Aurora branched on 4/12 and bug 616666 went in on 4/26. So we're good. It would be nice if there were a web page that listed the time and changeset id of each branch. Maybe there's an easy way to figure this out, but I ended up just searching through hg.mozilla.org, which is pretty annoying.
