@fs: Could you please look into the issue, and if it has nothing to do with your changes and if possible please do assign it to the concerned owner.

Thank you.

My change was to LineBoxList::hitTest (not LineBoxList::deleteLineBoxTree), but this looks like a case of to deeply nested content which eventually ends up exhausting the stack. I'll see if I can dig something out of the TC though.

Running the TC in a debug build, it crashes during attach already with very deep tree.
