readline set's these variables in shell.c:sh_set_lines_and_columns. This gets called from terminal.c:_rl_get_screen_size which get's called from terminal.c:rl_resize_terminal. It also get's called from terminal.c:_rl_init_terminal_io. The best way to resolve this problem is to get a version of bash compiled with debug and set breakpoints at the places I've mentioned..
