 Priority:  normal       |   Milestone:  6.5.0                    
Component:  Raster       |     Version:  svn-develbranch6

-------------------------+--------------------------------------------------
 I used r.in.wms to download high resolution topographical maps from local
 WMS service. Download part went just fine but it resulted into 287 tiles.
 Then r.in.wms calls r.in.gdalwarp
 input=/home/maris/grassdata/wms_download/topo_10k_psrs_0.png and so on 287
 tile names. Such call results in buffer owerflow in g.parser:
