Just to note that this does not seem to be an isolated problem:
* http://lists.osgeo.org/pipermail/grass-dev/2014-September/070584.html
* http://lists.osgeo.org/pipermail/grass-dev/2015-May/074937.html
Right. And as in those two cases, when I do not use a mask, I do not
have the problem, but calculation times are increased which makes it a
pain to work without a mask.
The error comes from here:
raster/get_row.c:142: G_fatal_error(_("Error reading raster data for row
%d of <%s>"),
which is part of the 'read_data_compressed' function.
read(fcb->data_fd, cmp, readamount) returns 0, while readamount is 18.
I'm not familiar enough with the raster lib to understand what this implies.
