Description:

    If I start bash in UTF-8 locale, then run set, bash dies as shown below.
    This does not happen if I change to UTF-8 locale after I start bash, 
    but it does happen if I start bash in UTF-8 and change to another locale
    before running set.

    Program received signal SIGABRT, Aborted.
