Follow-up Comment #10, bug #20003 (project freeciv):
> I see two possible ways to fix this.
Well, third one is what I've planned to do for a long time*: give
dio_get_xxx() functions return values telling if they succeeded or failed.
Patch attached.
*) According to very old TODO I had actually foreseen possibility of infinite
loop somewhere when I first came across the dio_get_xxx() functions and
noticed their lack of return value.
Any volunteers to do throughout checking of all dio_get_xxx() callers in case
there's other places where return values (added by this patch) should be
checked.
