It appears that the author didn't quite understand the command-line
parser. That argument has:

    parm.output->gisprompt  = "old,cell,raster" ;

which tells the parser that the "output" argument is the name of an
existing raster map layer (it isn't; it's a filename).

I'll commit a fix to this.

r.in.ascii may have a bug, but it's not the same bug. Only "output"
has a "gisprompt" value.
