#3062: Segmentation fault with r.buffer
----------------------+-------------------------
 Reporter:  escheper  |      Owner:  grass-dev@…
     Type:  defect    |     Status:  new
 Priority:  blocker   |  Milestone:  7.0.5
Component:  Raster    |    Version:  7.0.4
 Keywords:  buffer    |        CPU:  Other
 Platform:  Linux     |
----------------------+-------------------------
 I'm trying to buffer raster regions at various resolutions. The following
 commands went well:

 {{{
 g.region w=-180.0 s=-90.0 e=180.0 n=90.0 res=0.00833333

 r.buffer input=rasset output=rasbuf distances=10.0 units="kilometers" --o
 }}}

 The next commands give a segmentation fault at "Finding buffer zones..."
 (at around 37%).

 {{{
 g.region w=-180.0 s=-90.0 e=180.0 n=90.0 res=0.002777777

 r.buffer input=rasset output=rasbuf distances=10.0 units="kilometers" --o
 }}}

 I'm using Ubuntu 16.04 LTS on an Intel Xeon E5-1650 server with >64GB
 memory.

 Does anyone have a workaround or an idea what the cause is?
