Comment (by ThomasDickey):

 I found the problem; it is simple to explain.  ncurses uses the symbol
 MB_LEN_MAX,
 which has a fallback definition in limits.h -- which is too short to use
 -- while
 the "real" definition is lacking in gcc13 (since I've encountered the
 problem on
 three machines, that rules out "environment stuff").  The effect of the
 too-short
 definition is a buffer overrun.  I'll make a workaround in ncurses, but it
 would
 be nice to fix the port.

 (I'll see if I can find where the proper definition comes from in gcc12).
