How odd.  I tried this on my system which was last updated June 14 last
year and both running gdb then doing tui enable or just running gdb -tui
Just Works(tm).

I have gdb:

I guess I will have to update and see what happens.

Pad being NULL is a Bad Thing.  That variable should contain a pointer
to a WINDOW structure.
