[New-bugs-announce] [issue21390] strdup may cause Segment Fault on Android

[Li Zhenhua]

New submission from Li Zhenhua:

On Android platform, when run "python" command without any scripts, it may crash, get an error message "Segment Fault". This is because strdup with a NULL pointer. 

Details:
In file 
    Modules/readline.c, 
function
    static void setup_readline(void)

This line:
    char *saved_locale = strdup(setlocale(LC_CTYPE, NULL));

When running on an Android platform, setlocale(LC_CTYPE, NULL) returns NULL, and this causes strdup with a NULL pointer, then Segment Fault occurs.
