Running MAY 10 version  
Segmentation fault  
-------------------  
 
This applies to many 6.x versions (including stable) and also to 32bit 
installations (including precompiled ones). 
 
 
The input maps "rain", "manin" and "infil" have been created artificially as  
constant fields by the following script:  
-------------------  
#!/bin/sh 
dem=elevation.10m  
g.region rast=${dem}  
r.slope.aspect --o elevation=$dem dx=${dem}_dx dy=${dem}_dy  
r.mapcalc "${dem}_rain=if(${dem},0.0001,null())"  
r.mapcalc "${dem}_manin=if(${dem},0.04,null())"  
r.mapcalc "${dem}_infil=if(${dem},0.9,null())"  
  
echo r.sim.water  elevin=${dem} dxin=${dem}_dx dyin=${dem}_dy \  
rain=${dem}_rain manin=${dem}_manin infil=${dem}_infil \  
depth=${dem}_depth disch=${dem}_disch  
  
r.sim.water  elevin=${dem} dxin=${dem}_dx dyin=${dem}_dy \  
rain=${dem}_rain manin=${dem}_manin infil=${dem}_infil \  
depth=${dem}_depth disch=${dem}_disch

Many thanks for looking at it,
