QMap destructor got CRT detected message

[hosseinzolfi]

Iam getting CRT Heap corruption detected message, when running the following simple c++ code. The error comes from ::free method called by QMap destrcutor.

void foo() {
    QMap<QString, QVariant> map;
    map["Sample1"] = 2;
    map["Sample2"] = 3;
}

void foo() {
    QMap<QString, QVariant> map;
    map["Sample1"] = 2;
    map["Sample2"] = 3;
}

I am using Qt 5.5.1 (It built Qt with Visual Studio 2013 and configure it to target windows xp(using v120_xp toolset)).

Preconditions:

My operating system is Windows 8 64 bit.
I changed the Platform Tools property to Visual Studio 2013 - Windows XP (v120_xp).
When I change the code to following, the error is gone.

void foo() {
    QMap<QString, int> map; // Change the second type from QVariant to int
    map["Sample1"] = 2;
    map["Sample2"] = 3;
}

void foo() {
    QMap<QString, int> map; // Change the second type from QVariant to int
    map["Sample1"] = 2;
    map["Sample2"] = 3;
}

To copy to clipboard, switch view to plain text mode 

Any help will be appreciated.
