[Bug-readline] readline 6.3.8 dies

[Arkadiusz Miśkiewicz]

bash-4.3.30
readline-6.3.8

on linux/x86_64

It happened on cd some_SVN_directory<tab for completion> (where it took some 
longer time)
and I interrupted it via ctrl+c.

Unfortunately I don't have core dump, so probably not helpful but here it is 
anyway.
Tried to reproduce but failed.

Happened twice in ~ one month.
