     Type:  enhancement                |     Status:  new
 Priority:  normal                     |  Milestone:  7.0.1
Component:  Default                    |    Version:  svn-trunk
 Keywords:  r.neighbors large rasters  |        CPU:  x86-64
 Platform:  Linux                      |
---------------------------------------+-------------------------
 running r.neighbors --o --verbose input=naip_change
 output=naip_change_average method=average size=29

 The input raster is  ( r.info output)

 Total Cells:  365659744068
 Starts and shows 0% complete, then crashes with segmentation fault.

 linux top program  shows process using 1.5 GB RAM before crash

 Using
 grass-7.0.svn_src_snapshot_2015_05_02

 In main.c , line 139 I see :
 int i , n;

   I assume that this means that r.neighbors is limited to rasters with the
 number of cells in the 32 bit integer range?
