I have tested with your provided files and MD5-summ from your maschine.

The differ from mine. Here are some results, which I cannot clearly

My maschine: AMD Sempron(tm) 2600+

The command (taken from spearfish60 in user1-mapset):
g.region res=150 res3=150 t=80 b=0 tbres=10
v.buffer input=bugsites at PERMANENT output=bugsites_buff buffer=200

The md5sum from Soeren calculated at my maschine:
md5sum /home/holl/soerens_files/bugsites_buff/*
3c3b6801aa755149eb22954b925f44da  /home/holl/soerens_files/bugsites_buff/cidx
99c750d7ae0868f2cf2cee868ca5a3ae  /home/holl/soerens_files/bugsites_buff/coor
dcd038557184668b58c37a7b04492306  /home/holl/soerens_files/bugsites_buff/topo

the md5-sums calculated at soerens maschine:
3c3b6801aa755149eb22954b925f44da cidx
99c750d7ae0868f2cf2cee868ca5a3ae coor
dcd038557184668b58c37a7b04492306 topo

My calculations and my md5-sums:
md5sum /home/holl/grassdata/spearfish60/user1/vector/bugsites_buff/*
7511344bb7b329a264aa04c27075a8af  /home/holl/[...]/bugsites_buff/cidx
0f55a9ae0dd50a124b220e47e6d9b995  /home/holl/[...]/bugsites_buff/coor
6dd48f3002358e57b388bf7568f8d27f  /home/holl/[...]/bugsites_buff/topo

They all do not match!

Filesize of coor differs!

-rw-r--r--  1 holl users  19508 2006-01-25 11:51 bugsites_buff/topo

File-output: Soerens output
cidx: Hitachi SH big-endian COFF object, not stripped
coor: PDP-11 old overlay
topo: Hitachi SH big-endian COFF object, not stripped

file /home/holl/[...]/bugsites_buff/*
cidx: Hitachi SH big-endian COFF object, not stripped 
coor: PDP-11 old overlay 
topo: Hitachi SH big-endian COFF object, not stripped

> Any help or suggestions are welcome,

What else could be the problem?
