Buggy Calculator

Intentionally broken calculator app, based on Qt 5.6 Calculator example. http://doc.qt.io/qt-5/qtwidgets-widgets-calculator-example.html

Note that the crashes only work when compiled in debug mode. The contents of the zip file in dist-debug directory should provide the desired functionality. As is, on Windows.

SPOILER ALERT! Do not scroll below this bicycle if you want to explore and find all the 10 issues with the software yourself. They're not necessarily all bugs in a strict sense, mind you.
