 Using the NC demo dataset, I have the following issue with
 i.segment.hierarchical (in fact the GridModule):


 {{{
 g.region rast=ortho_2001_t792_1m
 i.group ortho in=ortho_2001_t792_1m
 i.segment.hierarchical group=ortho thresholds=0.01,0.02,0.03
 output=seg_ortho_out outputs_pref=seg_ortho memory=2000 width=1524
 height=1524 processes=4
 }}}

 Result:


 {{{

 Anna already reported such an error on the mailing list
 [https://lists.osgeo.org/pipermail/grass-dev/2015-November/077357.html 1],
 but I haven't seen a response. And contrary to what she reports, I have
 this problem systematically, not in random manner.

 I also tried reducing the number of processes, but to no avail.
