[Freeciv-Dev] (PR#6831) [CVS 2003-11-10] GTK+ Client Memory Allocation failure

["awilkins@xxxxxxxxxxxx" <awilkins@xxxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=6831 >

Platform information:

linux 2.4.20-20.7 i686
gtk+ 2.0.2
imlib 1.9.13
glib 2.0.1
gcc 2.9.6 and 3.3

I have a fairly large saved game (around 1600 cities; 2700 units).  I 
start the server using this saved game, start the client, connect, and 
then start the game.  The output from the client is as follows:

1: Cannot find sound spec-file "stdsounds".
1: To get sound you need to download a sound set!
1: Get sound sets from 
<ftp://ftp.freeciv.org/freeciv/contrib/sounds/sets>.
1: Will continue with disabled sounds.
2: LANGUAGE="en-us"
0: Detected fatal error in mem.c line 41:
0: Out of memory trying to malloc 1684370035 bytes at line 226 of 
attribute.c.
civclient: shared.c:665: real_die: Assertion `0' failed.

The save file is located at:

http://www.stanford.edu/~awilkins/game-09-+0987a.sav.gz

For comparison purposes, I also have a slightly earlier version of the 
save file which doesn't cause the client to immediately crash on 
connecting; it is at:

http://www.stanford.edu/~awilkins/game-09-+0987.sav.gz 

It strikes me that the amount of memory that the client is attempting to 
allocate here (over 1 1/2 GB!) is excessive, to say the least, 
especially given that I was able to play up to the point of generating 
the save file.  However, I don't know enough about the specifics of what 
FreeCiv is allocating memory for to determine exactly why this is 
occuring.
