[Qt-interest] Segfault when appending to QList

[Vedran Furač]

Hi,

I'm probably missing something obvious, anyways here's the (simplified)
code:

QList<QPair <int, int> >* foo;

// Passing it to Bar's constructor:

Bar(foo); // Bar inherits QThread.

Bar::Bar(QList<QPair <int, int> >* foo)
    : foo(foo) // Foo* foo; in private: in .h

{   QPair<int, int> bla;
    foo->append(bla);  }

This results with:

Program received signal SIGSEGV, Segmentation fault.
0x0000000000403c8b in QBasicAtomicInt::operator!= (this=0x1f, value=1)
at /usr/include/qt4/QtCore/qbasicatomic.h:75
75              return _q_value != value;

(this=0x60b700, t=...) at /usr/include/qt4/QtCore/qlist.h:468
foo->append(bla); line

TIA!

Regards,
Vedran
