    I have made simple QML application and I want to make a UI test for that.

    When I let the test running it works fine, even printing to the standard output works fine. However when I set a break point in the javascript testcase and I access one of the QML elements from the script, the Javascript debugger crashes with a stack overflow error.

    I use

    • QT 5.5.0
    • QTCreator 3.4.2 Opensource
    • CDB C++ debugger: it works stable it even catches the crash in the Javascript debugger
    • Platform 32bit/64bit: The javascript debugger crash occurs for both platforms

    It would make sense to attach the QT project to the bug. I am not sure if possible....
