      When experimenting with qt_add_qml_module I (accidentally) came up with this CMakeFile:

      qt_add_qml_module(MCGui
    URI MC.Gui
    VERSION 1.0
    NO_PLUGIN
    ENABLE_TYPE_COMPILER
    IMPORTS
    MC.Gui
    QtQuick
    QtQuick.Controls
    QtQuick.Controls.Basic
    QML_FILES
    Some.qml
    Files.qml
)

      Note that MC.Gui imports MC.Gui (itself.)

      It made my Qt Creator crash because of an infinite loop. It does not crash when removing the offending line.

      Please find the backtrace attached. It seems that QmlJS::LinkPrivate::importLibrary is calling itself recursively without protection against infinite loop.
