[GRASSLIST:2766] r.terraflow on a X,Y location

[SWlab]

Hello,
I try to run "r.terraflow" (GRASS53 on a SuSE8.2 box) on a small location. I 
get this error message:
#-------------
WARNING: grid larger than memory (ignored)
r.terraflow: grid.cc:56: grid::grid(short int, short int, short int, short 
int, long int, int): Assertion `width*height*sizeof(gridElement) < 
getAvailableMemory()' failed.
#-------------

What surprises me is that "r.terraflow" runs without problem on larger 
locations (in all cases, I precise a max memory value with the "mem" option).
The location with problems is in X/Y system, when the others were in UTM. 
Would this mean that, because I don't any PROJINFO information (after all, 
I'm in X/Y location), r.terraflow can't access "width" nor "height" nor 
"res"? But then, why not using the size of the DEM (an obvious mandatory 
argument), where 'width' and 'height' would be defined by the size of the 
map? Is there any workaround ?

Any idea/comment more than welcomed.
Thanks in advance

P.
