Hi,
|
|
|
|
I finally figure out why kxmame mysteriously crashes using qt 3.3.5. This
|
|
is because QListView::clear() method doesn't reset d->highlighted to NULL.
|
|
|
|
This means that after a few tries of clearing and repopulating the item
|
|
list, d->highlighted might point to an invalid location. When
|
|
QListViewItem::takeItem is called, d->highlighted is used and causes
|
|
crash. Remarkably, due to the way it's coded, this bug doesn't appear in
|
|
Qt 3.3.4.
|
|
|
|
I included the fix patch below for your information. I don't want to
|
|
subscribe to another qt-devel list to send this bug info. So if anyone
|
|
here can help sending this patch to the proper place, please do.
|
|
|
|
Thanks a lot,
|
|
Toan
