eh? my point was mearly that there are some existing memory bugs
which haven't been fixed yet as they only present themselves when
run under MS Windows, and we are just starting to discover those
as more people try native WinGrass.

I've got no idea if this problem belongs to that class or not,
nor if XP vs. Vista makes any difference to GRASS. Just that
Valgrind is a nice tool for helping to deal to bugs stemming
from memory code mistakes, or clearing that as a suspected
cause.
"Hamish suggested that this may be a generic problem on MS windows (vista)" might have been better phrasing. Sorry for misinterpreting your words!

In this particular case, it may be a problem of a 32bit application running on a 64bit system with more than 3GB RAM, causing rather ugly out-of-memory errors because the 32bit application requesting more memory can't handle the memory returned by the OS. Just a wild guess, maybe a windows developer can say more about it.
