Comment on attachment 545397 [details] [diff] [review] Patch v1 - In nsTextFragment::SizeOf(): + PRInt64 size = sizeof(*this); + size += GetLength() * Is2b() ? sizeof(*m2b) : sizeof(*m1b); We should only add the size of the text itself if mState.mInHeap is true, if not, it's a text fragment that points to a shared static whitespace string. r=jst with that.
this has been backed out by ehsan due to bustage with all the other changesets in the same push
