[GRASS5] r.null bug or gis library bug?

[GRASS]

hi all,

r.null has bug:

	r.mapcalc "tmp=2.0"
	r.null map=tmp setnull=2.0

Floating exception error occurred.

1. Size of f_range file changes to zero while running r.null.

2. G_number_of_cats()	called on line 316 in src/raster/r.null/null.c

3.  G_read_range()      called on line 395 in src/libes/gis/cats.c

4.   G_read_fp_range()  called on line 209 in src/libes/gis/range.c

5.                      returns 2 on line 156 in src/libes/gis/range.c
				because f_range size is 0.

6.  G_get_fp_range_min_max() set drange->min, drange->max to NULL
				as drange->first_time == 1

7.  Now, trying to assign double NULL value(means NaN) to integer var.
	==> BUG



does anyone have idea?
