[Freeciv-Dev] Sulky Stealth Syndrome

[swamp-dog@xxxxxxxxxxxx (Guy Harrison)]

Hi Folks,

Cygwin/XFree86[+mingw SDL/SDL_Mixer], rebuilt from CVS 24..36hrs ago.

Air units (well Stealth bombers & helicopters) cause civclient to
(spuriously) crash when opening up unexplored map. Visually it *seems*
as though it's connected to the unit encountering some previously
unencountered city/"terraformed" square. Client can reconnect and
continue fine so after a few of these crashes I ran it under "gdb -nw".

Btw, "Goto" isn't working very well - keeps giving up and flashing the
unit. It isn't working at all for Stealth bombers (moves one square & no
line drawn at all).

Three client crashes (server continually running same game)...

...er, and it may only occur when unit is moving south-west but forget I
said that!
