OK, my first attempt to use civclient on my Alpha box is somewhat
disheartening :-(

The problem is that the error is apparently happening DEEP inside some 
X code, and I am not at all fluent in Xt/Xaw so I can't be of much use 
there.  However, I can try and pinpoint some stuff with gdb.

Configuration details below.  Here's some gdb info:

(gdb) run
Starting program: /usr/games/civclient.real 

Program received signal SIGSEGV, Segmentation fault.
0x155561e50b8 in strcmp ()
(gdb) bt

(gdb) print map_canvas
$1 = 0x1201e8030
(gdb) print XtNheight

(gdb) print h
$2 = 21953
(gdb) print XtNwidth

(gdb) print w
$3 = 41184
(gdb) frame 4
#4  0x1200096d8 in main (argc=1, argv=0x11ffffd08) at civclient.c:88
88        x_main(argc, argv);
(gdb) print argc
$4 = 1
(gdb) print argv
$5 = (char **) 0x11ffffd08

Now then.  This machine is an Alpha 21164 (64-bit 600MHz) box running
Linux 2.0.35 (Debian slink/potato).

ldd reports, for civclient:

        libnsl.so.1.1 => /lib/libnsl.so.1.1 (0x000001555555a000)

        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x0000000000000000)

Also an odd behavior with civserver: it cannot seem to do a reverse
lookup on people; it lists everybody as being connected from
"unknown".  Other programs do not have this problem.

And a final detail: if I run civclient on my Pentium box, and direct
the DISPLAY to the Alpha, things work fine, so it's not a problem with 
the Alpha X-server (I don't think.)

Let me know what I can do to help diagnose this problem!

Thanks,
John
