[Xastir] Crash on 64-bit FC3

[Jim King]

I'm running FC3 test 2, Xastir source pulled from CVS yesterday.  I 
suspect this is an FC3 bug, but I'm an X11 noob.  Xastir crashes with a 
segmentation violation.  In gdb I get:

(gdb) bt
#0  0x0000003b07c4d061 in _XtCountVaList () from /usr/X11R6/lib64/libXt.so.6
#1  0x0000003b07c4cabe in XtVaGetValues () from /usr/X11R6/lib64/libXt.so.6
#2  0x0000000000473925 in da_expose (w=0x8b9960, client_data=0x3b00000000,
    call_data=0x7fbfffe7f8) at main.c:9069
#3  0x0000003b07c13fa5 in XtCallCallbackList ()
   from /usr/X11R6/lib64/libXt.so.6
[etc.]

It looks to me like the call from da_expose to XtVaGetValues is causing 
a segv.  Since this same code works on 32-bit Linux that led to me guess 
that this is a bug in 64-bit FC3, unless maybe Xastir is using 
XtVaGetValues in a not-quite-sanctioned manner that happens to work on 
32-bit but not on 64-bit.

If somebody can confirm that Xastir's use of XtVaGetValues is OK I'll 
submit a Fedora bug.  Otherwise if somebody can suggest some variations 
on the function call to try I'll do that.
