Apparently because their loader is lazy; the symbol lookup error only
occurs then only if you use a high debug level in tic (option -v2 or
higher). See #365120.

It definitely is a bug in the packaging, but I'm not sure how to best
resolve it. My favorite solution would be to build the regular
libraries without -DNDEBUG and use detached debugging symbols instead of
extra libraries in the -dbg packages. However, this is a rather radical
change. Minimally obtrusive might be this patch:

This solves the problem of the symbol lookup error, but makes it harder
to debug the programs in ncurses-bin, because they are built with -DNEDUG
and without -DTRACE.
