v.surf.rst fills up all available hard drive space when region is not set

[Stephan66]

When v.surf.rst is called and no region has been set (i.e. using g.region), it will fill up all available storage space in my grassdata directory (~ 130 GB in just a few minutes....).

There's always a region. Please run g.region -p and report results here.

g.region -p

I'm sorry. v.surf.rst just does what You have ordered. It would create a raster with 73665360000 cells, that would take approx. 550 Gb of RAM/disk (rough calculation without taking into account any compression or overhead). Next time just check Your region settings before performing any analysis.
