 Hi,

 v.to.rast segfaults in G_close_gdal_link() when used with a FP
 attribute column.

 {{{
 #spearfish
 v.random out=rand1k_elev n=1000
 v.db.addtable map=rand1k_elev column='elevation double precision'
 v.what.rast vector=rand1k_elev raster=elevation.10m column=elevation
 v.to.rast in=rand1k_elev out=rand1k.elev use=attr column=elevation

 Converted areas: 0 of 0
 Converted points/lines: 1000 of 1000
 Segmentation fault
 }}}

 output map looks ok on causal look.

 presumably introduced with r.external changes.
