#3634: r.horizon: segmentation fault/bus error when raster using wrong
geographical coordinates

-------------------------+-------------------------
While trying to use the tool on a SRTM (N45E007), I was confronted with a
segmentation and bus error. My mistake was inverting lat/lon...

Here's my procedure to reproduce it.

> r.horizon elevation=N45E007 coordinates=45.737698,7.361012 step=5

{{{
Note: In latitude-longitude coordinate system specify buffers in degree
unit

39437 bus error (core dumped) r.horizon elevation=N45E007
coordinates=45.737698,7.361012 step=5
}}}

> r.horizon elevation=N45E007 coordinates=45.737698,7.361012 step=0
direction=215 bufferzone=1 maxdistance=5000

{{{
Note: In latitude-longitude coordinate system specify buffers in degree

39574 segmentation fault (core dumped) r.horizon elevation=N45E007
coordinates=45.737698,7.361012 step=0
}}}
