This is a way to crash the editor when compiling (a large) project:
Open "Samples\__Projects__\DDgui\DDgui.gbap" and make sure all files are open in the editor.
Press the compile button and then quickly close one of the open files.
When the compiler is done, the editor will crash. So far this works every time, on all projects I tried that are long enough for me to have time to close the window.
