OK I've eventually got OSGeo4W installed on a Vista machine (no idea if 
it's Vista related though) and tried it and I can reproduce the problem. 
It's not required to attempt to create a new location, simply
g.proj -p epsg=4326
is enough to reproduce the crash.
g.proj -w
prints the projection information in WKT format and *then* crashes. I'm 
guessing the problem is somewhere in the linkage with GDAL/OGR. Perhaps 
even related to the issue of freeing pointers with the correct function 
that was used to create them, that was reported a couple of months ago. 
But I thought we fixed that.

The next step is to compile GRASS from scratch on Vista to see if the 
problem is in GRASS or related to the OSGeo4W packaging. That could take a 
while but it needs done so hopefully it will get done.

Interesting for now would be if someone could test the same commands in an 
OSGeo4W install on a Windows-XP machine.
