BUG:	A segmentation violation (a reference to an invalid memory address)
	is possible because of a bug in a array length calculation.  This
	problem was seen with mscred.mscimage (which calls mscred.combine)
	on PC-IRAF.  Whether this occurs with other systems is unknown.
	The error occurs almost immediately.  There is no workaround if the
	error occurs.

STATUS:	A new version of mscred is available with the fix.  The next
	patch version of IRAF will fix the problem in imcombine.
