Re: [pbmserv-dev] help with Get/Set Options in game.cpp

[Richard Rognlie <rrognlie@gamerz.net>]

It's a static variable issue, I'd bet.

we return a pointer to inside the static char[] space.  If you've done
a subsequent call to GetOption, the earlier value is no longer valid.

you need to COPY the string returned from GetOption() before you call it
again.
