Is that something you might have changed recently? I will have a go at<br>
rebuilding VirtualBox to see if it still happens, and if so can provide<br>
the recipe. But it did look like the assertion was in Qt (I see it in<br>
the Qt source and not in our source!) By the way, the link you provided<br>
above was not very clear to me, how can I see from it how you have build<br>
Qt? I might be able to save everyone some time if I can take a look<br>
into things myself. And I don't suppose you might be defining<br>
QT_FORCE_ASSERTS? Or is there somewhere where QT_NO_DEBUG might be<br>
getting disabled again? (I will have a quick look in the sources too.)<br>
