r.sim.water crashes on WinGrass

Hello! Has anyone experience with using r.sim.water under Windows? I'm planning to use it for the simulation of flash flood events. I tried it with a DEM (1m resolution) with the following region setting: g.region -p rojection: 99 (Transverse Mercator) zone: 0 datum: potsdam ellipsoid: bessel north: 5377000.5 south: 5375999.5 west: 3502999.5 east: 3504000.5 nsres: 1 ewres: 1 rows: 1001 cols: 1001 cells: 1002001 I calculated the first order partial derivative dx and dy with r.slope.aspect (Do I have to use degrees in the settings?) Leaving everything else unchanged for a testrun, I get the following message and r.sim.water crashes: "r.sim.water.exe hat ein Problem festgestellt und muss beendet werden." ("r.sim.water.exe has detected a problem and has to be closed") Can anyone tell me what's going wrong? Would it be better to use GRASS under Linux for this purpose? Thanks for your help, Bernd
with "g.gisenv set="DEBUG=3" set I can see that it happens after "Running MAY 10 version," text. Next step in the program after that is to allocate memory...... so I'm guessing it's a malloc problem that is only triggered on windows, much like we saw in r.los in bug #111 (and I expect we'll see a lot more of these).
valgrind running now (slow),
