So either it's picking up some unexpected library, or there's some bug
to investigate.

You can make the debugging a little easier by configuring ncurses with
its tracing feature enabled (configure --with-trace).  The current
dialog program also has tracing (though less powerful).

By running the program in both environments with the tracing activated,
you may see some discrepancy between the two.  (I'm not sure what you
would find).

Given an application that's linked with ncurses+tracing, you can set
the NCURSES_TRACE environment variable, e.g,.

        export NCURSES_TRACE=0xffff

and the application writes to "trace" with the call/return information
and associated details.

Aside from pointer-values in the traces, they "should" be the same...
