[Qt-interest] QList is crashing when detructed?

[Eric Clark]

I narrowed this bug down to nedmalloc. My application overrides the default malloc to use nedmalloc. If I turn off nedmalloc, this crash does not happen. Has anyone attempted to use nedmalloc with Qt and ran into issues with QLists?

Subject: [Qt-interest] QList is crashing when detructed?

Hello All,

Can anyone explain why my code is crashing when a QModelIndexList returned from a call to QItemSelectionModel::selectedIndexes() is deleted? The code looks similar to this:

void Foo()
{
  QModelIndexList list = mySelectionModel->selectedIndexes();
  ...
}

I do actually do something with the list, but this code crashes even if there is only the one line in it. The code crashes in the destructor of the QList, it says that some memory is being freed more than once.

Any help would be greatly appreciated!

Thanks,
Eric
