If the dialog pluging is statically linked into the mariadb client app, it crashes when prompting for a password (-p),:
Program received signal SIGSEGV, Segmentation fault.

libmariadb/plugins/auth/dialog.c calls get_tty_password with three arguments, intending the 3-argument function in libmariadb/libmariadb/get_password.c.
When statically linked, the identically named function in mysys/get_password.c apparently causes the problem.
If the get_tty_password function is renamed in both libmariadb/plugins/auth/dialog.c and libmariadb/libmariadb/get_password.c, the mariadb client works correctly.
Bug
Minor
