HI
I’m getting the following error when using the r.to.vect module:
ERROR: G_realloc: unable to allocate 25440000 bytes at areas.c:678
I understand that this is due to the standard memory installation of 64mb of RAM allocation. How can i overcome this limitation.I also need to solve this on my Ubuntu 12.04 install

This error message is now hopefully more useful in 6.4.svn (i.e. 6.4.3 in the
very near future). Would you mind to upgrade to the nightly snapshot?:
http://wingrass.fsv.cvut.cz/grass64/
and try again? As a bonus it includes many more bugfixes.
We need to know if the better error message is triggered or not.
I understand that this is due to the standard memory installation of 64mb of
RAM allocation.
While GRASS may even run with 64MB RAM, you likely mean 64bit CPU (rather
than 32bit). To some extent, GRASS 6 offers large file support for raster data
while GRASS 7 aims at complete large file support for raster and vector data
on 32bit architectures.

To not leave you in the dark: the computation region
(http://grass.osgeo.org/wiki/Computational_region) will be either to large
or have too many raster cells active (too high resolution). So, in the first
place check the output of
g.region -p
However, please make the winGRASS test for us first, thanks!
