BUG:	Due to a typographical error in the file math$gsurfit/gsder.gx,
	dgsder (the routine which computes the derivative of a double
	precision surface) was inadvertantly calling salloc with a pointer
	address instead of an array size. If the assigned pointer value
	is very large this can cause an 'out of memory error' in any task
	which calls dgsder.

	Currently the only task affected by this bug is TRANSFORM
	in the LONGSLIT package.

STATUS: The bug is fixed in 2.10. There is no workaround. Contact NOAO for
	a fix.
