Comment (by mlennert):

 I can't reproduce this with the North Carolina demo data set:

 v.net streets_wake points=firestations operation=connect thresh=200
 echo "1 15 64" | v.net.path streets_firestations afcol=FT_COST out=myPath
 echo "1 15 64" > mypaths.txt
 cat mypaths.txt | v.net.path streets_firestations afcol=FT_COST

 v.db.select myPath

 v.db.select myPath2

 Your data is not usable as you don't define the projection system it is
 in, nor is the attribute table containing the arc_cost column attached.
 Best would be to either reproduce the bug with the demo dataset, or
 provide your example data as a complete location, including the sqlite
 database, or with a dbf attribute backend.
