The API for newwin() is documented as:
Calling newwin creates and returns a pointer to a new
window with the given number of lines and columns. The upper
left-hand corner of the window
is at line begin_y, column begin_x. If either nlines or
ncols is zero, they default to LINES - begin_y and COLS - begin_x.
A new full-screen win‐
dow is created by calling newwin(0,0,0,0).
But starting with ncurses 5.8, ncurses/base/lib_newwin.c has the
following code on line 144:
if (begy < 0 || begx < 0 || num_lines <= 0 || num_columns <= 0)
returnWin(0);
This causes a call of newwin(0,0,0,0) to return an error.
yes... I made the change because of a core dump (as called from
dialog, which assumed the window had rows/columns).
Which applications are making newwin(0,0,0,0) calls?
Newsbeuter does (via libstfl), segfaulting in the process because stfl
does not expect this to return a null pointer:

I see (now). I'll revert that.
