BUG:	A segmentation violation will occur when the 'crmask' parameter is
	set to an existing mask.  The intent was to allow an existing mask
	to be used to exclude known bad pixels from the calculation and then
	add the detected cosmic rays to the mask.  But a bug in the code
	prevents this from working.  The workaround is to not use an
	existing mask in 'crmask'.  If one wants to end up with a mask
	describing the detected cosmic rays as well as the previously
	determine bad pixels then specify a new mask and merge the
	detectected cosmic rays with the previous mask.  There is no
	workaround to allow using the pre-existing mask to exclude pixels
	from the calculation.

STATUS:	Fixed for the next release.
