>Description:
	I installed xfig from the ports.  When I run it on a remote
	XFree86 server it produces error messages of ``unaligned
	access'', after several thousand such error messages it
	dumps core.

	I tried with several different XFree86 servers running on
	several linux machines, all have the same problem.

	When running on an old Tektronix Xserver I do not get the
	error messages and xfig runs without coredump.

	Main difference is, that the Tektronix is running in 8 bit
	Pseudo Color and all Linux machines used 24bit True Color.

	If I undo the XPM related patches provided with the port
	the problem goes away.

	
>How-To-Repeat:
	Happens every time.
	
>Fix:
	Do not define USEXPM or USEXPM_ICON.
	See third change set of ``xfig/files/patch-aa''.
