The steps followed are pretty trivial: I run the code pasted below, looked at the plot in its window, right-clicked to open the menu and asked to save the plot as EPS. Now I cannot reproduce it myself, so I guess it must have been some sort of mess in the memory management (using Windows 10 that would not be surprising at all). In fact that's what I thought rightaway, I posted the question mostly in case it may be of interest for developers. Thanks for your interest!
