[Freeciv-Dev] Unaligned access with Xaw client

[Peter Berg Larsen <pebl@xxxxxxxxxx>]

Every time I use or press the scrollbar I get a unaligned access
warning. I have traced it to the my_XawScrollbarSetThumb function.

(gdb) print l_top
$1 = (long *) 0x11ffff1ec
(gdb) print sizeof(XtArgVal)
$2 = 8
(gdb) print sizeof(float)
$3 = 4

Is this what the comment to function adresses or is it something else?
