[Qt-interest] How to debug memory leaks in QT based application?

[Nicolas Rannou]

Hello,

We are developing an application based on different c++ libraries 
including QT.
When we want to track memory leaks in the application, we usually use 
Valgrind.

The problem is that as soon as we use something from QT in our 
application, Valgrind reports a lot of memory leaks inside QT (not 
related to our application)... So it is almost impossible to find the 
leaks I am interested in.

Do you know why Valgrind reports these leaks?
Do you know how to debug memory leaks in a QT based application?
(I would like to avoid writing a huge suppression file for Valgrind)
Is Valgrind well suited for that or would you suggest to use something else?

Thanks,

     Nicolas
