t.rast.what throw error while running on large number of maps

[spareeth]

The temporal module t.rast.what throw error when nprocs is not used, while running on large number of maps (10,800 raster input in my case). The error is:

Traceback (most recent call last):
  File "/usr/local/grass-7.1.svn/scripts/t.rast.what", line 526, in <module>
    main(options, flags)
  File "/usr/local/grass-7.1.svn/scripts/t.rast.what", line 266, in main
    mod(map=map_names, output=file_name)
NameError: global name 'map_names' is not defined

It works if I give nprocs option; for example nprocs=4

With smaller number of maps, with or without nprocs work fine.

I encountered the same bug with a STRDS of 422 maps, meanwhile another STRDS of 600 maps of the same size worked fine. passing nprocs resolved the issue as well.

Tested here in NC with 1000 maps:

for i in `seq -w 1 1000` ; do r.mapcalc expression="map_$i = 1" ; done
t.create output=test type=strds temporaltype=absolute title="test" description="test"
g.list rast pat=map_* output=list
t.register input=test file=list start='2000-01-01' increment="1 days" -i
t.rast.what coordinates=494637.096774,154319.556452 strds=test

all fine, no error reported. Closing.
