OK, the crash mentioned above is a double-free in ncurses, which is
linked into libreadline8.dll. While this is not a Hatari bug, I would
still prefer switching back the builds to an older version of
libreadline, also because of the backspace issue, which I didn't have
time to investigate further.
I also now know why it didn't always crash. After a few crashes because
of double-frees, the Program Compatibility Assistant of Windows 10 kicks
in, decides that this is a "shitty" application and switches it to a
more fault tolerant heap implementation. Therefore, after some tries I
stopped seeing the crash until I downloaded the next revision of Hatari,
which was then started again without these compatibility settings.

Christian
