Program crashes at QApplication::exec()

It might help if you actually posted some code instead of just stack dumps, and reduced your code to something that reproduces the problem.

I use a QList private data member in the model to store the data from the file, maybe it has something to do with this?

I'd say that was a pretty good bet.

I've found the problem, a really silly thing, i didn't return an invalid QVariant in the data() function of the model if it was another role different than DisplayRole. But i wonder why it worked fine in 32 bits...

QVariant TableModel::data(const QModelIndex &index, int role) const {
      if (role == Qt::DisplayRole){
      ...
      }
      return QVariant(); //I missed this
}

QVariant TableModel::data(const QModelIndex &index, int role) const {
      if (role == Qt::DisplayRole){
      ...
      }
      return QVariant(); //I missed this
}

Anyway, again, thanks for your answers!

Strange compiler settings - should be an error message.

Mmmm, i have gcc default, and qmake with these arguments: "-r -spec linux-g++-64 CONFIG+=debug", also default.

Ah, yes, that was at least one obvious error when you said you are seeing checkboxes.

Cheers,
