tgetent core dump on sco xenix

[The Super User]

A game was posted some time back called "puzzle". It doesn't work
under SCO Xenix development system 2.1.4g because if compiled with
small model, the single 64K segment isn't sufficient for all its
data, and if compiled under large model it core dumps along the lines
of the much simplified example that follows.

Can anyone explain this?

[root]/tmp:(1 ) % cat argle.c
#include <stdio.h>
#include <sgtty.h>

main()
	{
	char	buffer[1024];

	printf("%d\n",tgetent(buffer,getenv("TERM")));
	};
[root]/tmp:(2 ) % cc -Ml2e -o argle argle.c -ltermcap
argle.c
[root]/tmp:(3 ) % ./argle
./argle: Segmentation violation -- Core dumped
