games/ace crashes

on amd64, few days old snap (I can't upgrade now for some reasons..)

From games/ace a lot of binaries produce a segmentation fault:

/tmp $ canfield
Segmentation fault (core dumped)
/tmp $ freecell
Segmentation fault (core dumped)
/tmp $ golf
Segmentation fault (core dumped)
/tmp $ solitaire
Segmentation fault (core dumped)
/tmp $ taipedit
Segmentation fault (core dumped)
/tmp $ thornq
Segmentation fault (core dumped)
/tmp $ taipei
Segmentation fault (core dumped)


an egdb stacktrace for solitaire shows
