Sorry not to follow up sooner. I have had little time.

Starting from the command prompt with a map= option, it will create the
new vector map if necessary, but then immediately causes a Segmentation
fault.

Starting it from the cm line without any parameters, or starting it
with d.m opens the initial dialog (in which the name of the input vector
is specified). Upon entering a vector map name and clicking Run, a stack
dump file is written out (no error message is displayed).

In your subsequent email you wrote:

Indeed there does appear to be a problem, I get:

   GRASS 5.7.-cvs:~ > grep stdout *
   out.txt:v.digit.log:"exec v.digit -n map=fart >@stdout 2>@stdout"
   out.txt:v.digit.log:"eval "exec $cmd >@stdout 2>@stdout""
   grep: test: Permission denied
   grep: test.txt: Permission denied
   v.digit.log:"exec v.digit -n map=fart >@stdout 2>@stdout"
   v.digit.log:"eval "exec $cmd >@stdout 2>@stdout""

I am sure this is rudimentary to most of the readers of this list, but I 
am lost here. Anyone want to give me a more verbose explanation as to 
where, and why, stdout is being redirected?

In the mean time, I will look thru the emails that you referenced:
