I have this simple qt-program like:
int main(int argc, char *argv[]) {
::QApplication app(argc, argv);
::QWidget wgt;
wgt.show();
return app.exec();
}
When I run program with Address Sinitizer, it showed me this:

SUMMARY: AddressSanitizer: 13468 byte(s) leaked in 81 allocation(s).
Is this a problem? How I can cleanup output from this messages?
I read somewhere it isn't a memory leaks, but to difficult search real memory leaks, when you have this messages.
