Summary [Qt] Symbian runs OOM when rendering large texts

Created attachment 80626 [details] Test Case Using QtWebkit2.1 with QtTestBrowser on Symbian^3 devices runs out of memory if a paragraph contains more than 1MB of text. I create this bug to set this issue apart from 'downloading crashes'-bugs Bug 46746 and Bug 51165 . Memory usage has increased quite a bit from Qt 4.6.3 as bugreports related to this issue are regressions. Question is should we consider this as a serious issue and whether we should in the future optimise for smaller memory consuption instead of speed. It is almost impossible to bisect against QtWebkit using Symbian so finding if there is a set of commits causing this is difficult :S

If I understand the backtrace correctly, this crashes OOM when allocating the inline box for the render tree. I think killing the app in that situation is a reasonable thing, if you can't render the page, close the app. What do you expect from this bug report?

Won't fix since there are no way to handle those cases nicely.
