[GRASS-dev] Error with r.to.vect- Solved?

[António Rocha]

Hello Markus
Unfortunely, I get this error when I run other datasets. In this case, a 
landCover with all CELLS and spatial resolution of 30. The problem is 
that North carolina sample is too small.
r.to.vect -v input=FULL at PERMANENT output=FULL feature=area
I get this:
Default driver / database set to:
driver: dbf
database: $GISDBASE/$LOCATION_NAME/$MAPSET/dbf/
Extracting areas...
Building topology for vector map <PT_National_2000_FULL>...
R4243000ERROR: G_realloc: unable to allocate 16976004 bytes at 
struct_alloc.c:133

It has created a vector but I cannot display and I cannot use v.info (it 
says that I need to build topology).
And If I try to build topology I get and error and before this warning:
Coor files of vector map <PT_National_2000_FULL at PERMANENT> is larger 
than it should be (241464079 bytes excess)

So my questions are:
1- Is any fix for this?
2- If not, is there any defined limit for a raster in order to be 
converted to vector?

Thanks
Antonio
