Perhaps the message you refer to was a report of a bug in tgetstr().
I thought I had saved the original message, but I can't find it, so I
can't say who it was that posted it.

This bug must be compensated for to get running any program that uses
it, including (for instance) JOVE.  tgetstr()'s second argument is
supposed to be the address of a pointer to a buffer.  The bug is that
it is implemented as if it is the actual pointer.  For example, here's
the workaround in JOVE's term.c module:

	=====

	for (i = 0; meas[i]; i++) {
#ifdef	UPORT_CURSES_BUG
		*(meas[i]) = (char *) tgetstr(ts, termp);
#else
		*(meas[i]) = (char *) tgetstr(ts, &termp);
#endif
		ts += 2;
	=====
