BUG:	Linmatch could crash with a floating operand error if the bscale scaling
	algorithm was one of 'mean', 'median', or 'mode', and the reference
	image contained one or more regions with a zero-valued mean, median,
	or mode. The error was in the computation of the error in the bscale
	value.

STATUS:	Fixed for the next release of iraf. The only work around is to choose
	the regions used for scaling carefully.
