The core dump is caused by an array overflow.  The routine _amove
contains the declarations:
	char rel[MAXPLEN + MAXLLEN + 50];    /* longest move is full screen */
	char ho[MAXPLEN + MAXLLEN + 50];

This code assumes that all relative cursor motions can be performed
using a single character sequence.  This assumption is reasonable for
horizontal motions but not for vertical ones.  A simple fix is to
change the array sizes to "MAXPLEN * 2 + MAXLLEN + 50", which will
probably work for almost all terminals.  A better fix would of course
be to have the plodput routine check for overflow of array bounds.
