Chet Ramey left as an exercise for the reader:
Readline provides defaults for rl_instream and rl_outstream the first time
it's called. These are in place before the first time rl_prep_terminal is
called. If an application using readline decides to change the file pointer
assigned to either of these variables, readline allows it.
Hrmmm. I definitely was crashing within rl_prep_terminal() (as
noted with valgrind) until I set this. I'll look deeper into how
this was happening, but gdb verified that rl_outstream was NULL
when the writeouts at the end of this function were hit.
Are you calling rl_prep_terminal directly, or letting readline call it for
you? If you call it before readline can initialize, or are calling it
without calling rl_initialize, all bets are off.
