QList: unexplicable crash

[pucara_faa]

Hi everybody,
I'm having problems when using QList to generate run-time widgets. I create those widgets and store them inside the QList for later use.
In one of my dialogs I need to create one QSpinBox and one QLineEdit dynamically. When I create them, everything works fine, and they are shown, but when I close the dialog, the application crashes. Here's the explanation of what I'm doing:

I create in my header file the QList variable as following:

private:
QList<QLineEdit*> products;

And I use it in in the source file like this:
QLineEdit *qleProducts = new QLineEdit();
qleProducts->setCompleter(completer); //Sets widget custom completer, defined before, it works OK
layout->addWidget(qleProducts); //Adds the widget to a layout
products.append(qleProducts);

Then, compile, and everything works OK.
But the problem comes when I try to create another QList object.
In the header file I add:
QList<QSpinBox*> totals;

And in the source file:
QSpinBox *qsbTotals= new QSpinBox();
layout->addWidget(qsbTotals);
totals.append(qsbTotals);

Then, I compile the application, it compiles OK, I execute the dialog, creates and display the widgets OK, but when I close the dialog, the application crashes, returning code -1073741819 but no other error.

It seems that the program crashes when I have declared two QList variables in one file.
Maybe it is a QT bug, or I'm just missing something stupid.
Please, I need help, I really need to solve this.

I'm sorry for my poor English, I'm Argentinian.
Best regards,
Facundo

Don't see why what you described won't work. Can you post your project as an attachment?

Thanks for answering!
Ok, I'll post it tomorrow, now I haven't the project in this computer.

Possible double free issue? Are you delete'ing those objects yourself as it seems they have no parent. If so, remove that code and see if it still crashes.

Hi,
First of all, I want to thank both of you for answering, I solved the problem, (although don't know HOW). I changed the code a little and then rebooted my computer and WORKED! :cool:
I don't know what could it be.
Kind regards,
