I was able to reproduce the bug:

Spearfish:
g.region rast=elevation.dem
r.mapcalc "elev.float = elevation.dem * 1.0"
r.fill.dir in=elev.float elev=blah dir=dir

The bug appears in get_min() which is called in
raster/r.fill.dir/ppupdate.c
row 134

The second parameter to get_min() seems to be empty when
it crashes.

However, I don't know how to fix it.
