QT Crashes with "!"empty Value encountered"" in file jsruntime\qv4value.cpp, line 142

[Eluvatar]

Hi, I'm using a 3rd party js library and I ran into an issue.

I've boiled it down to the following code that can reproduce the issue:

Component.onCompleted:  {
    var a = [];
    a[0] = 1;
    a[2] = 3;
    test.apply(null, a);
}

function test(a1, a2, a3) {
    print(a1);
    print(a2);//crashes here
    print(a3);
}

• Has anyone else experienced this issue?
• Can you reproduce it?
• Should I report this issue?
