Description Geoffrey Garen 2006-05-20 14:00:55 PDT
You can see the evolution of this crash most clearly if you set a  breakpoint on ~RenderTextField. You'll notice that RenderTextField::text() ends up calling RenderTextField:~RenderTextField, so the RenderTextField destroys itself.

The issue here is that the RenderTextField accesses innerText() on its associated HTMLElement. That access can force a recalcStyle, which can destroy the renderer.

Turning MallocScribble on makes this 100% reproducible.
Comment 2 Adele Peterson 2006-05-20 16:25:41 PDT
Shoot.  I just changed RenderTextField::text to use innerText instead of textContent so it would take whitespace into account for textareas.  We can change it back for now until we come up with a better solution to the whitespace problem.

Comment 5 Geoffrey Garen 2006-05-22 09:58:44 PDT
I think another solution might be to have the text() method update layout on the element itself instead of the whole document, which would prevent the element from being removed from the document. I don't understand the comment explaining why text() needs to update layout on the document, though, so I'm not sure that's a viable approach.
