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
Maybe some off_t issue?
Please post the region settings and related info...

Here's the error:
ERREUR: Error reading raster data for row 239 of <MASK>
Traceback (most recent call last):

Process ended with non-zero return code 1. See errors in the (error)
output.
And here the info for the two maps in the r.mapcalc call:
> r.info -g firm_rate_364596
north=3177000
south=2937000
east=4071000
west=3790000
nsres=1000

> r.info -g sum_rates
north=3177000
south=2937000
east=4071000
west=3790000
nsres=1000
ewres=1000
rows=240
cols=281
cells=67440
datatype=DCELL

But running the same script on the same maps, the error always appears
at a different stage (other firm_rate_* map).
