gh-120378: Fix crash caused by integer overflow in `curses` (GH-124555)

This is actually an upstream problem in curses, and has been reported
to them already:
https://lists.gnu.org/archive/html/bug-ncurses/2024-09/msg00101.html

This is a nice workaround in the meantime to prevent the segfault.

(cherry picked from commit c2ba931318)
