[Freeciv-Dev] civclient segfaults on startup (PR#35)

[garyc@xxxxxxxx]

Full_Name: Gary Cameron
Version: 1.8.0
OS: SuSE Linux kernel 2.2.10
Submission from: (NULL) (137.186.208.8)


The configure script appears to work correctly, and the code compiles without
error.
The civserver seems to start up ok, but the civclient always segfaults after
startup.
when I run  the civclient with debug messages enabled, I get the following
bash-2.02# ./civ -debug 2
2: Booting help texts
2: color system booted ok.
Segmentation fault
bash-2.02# 

        This game looks really cool, but I have no idea why it isn't working.
Are there any tests you could suggest to determine why it is crashing?

I am using SuSE 6.0 Linux with kernel 2.2.10

./configure generates the following:  (Sorry about the long listing - I hope it
helps)
