This returned this error message on my system: v.out.ascii(44851) malloc:
*** error for object 0x102013dc0: incorrect checksum for freed object -
object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6
Unable to really figure what was going on here I started to look for
alternatives to solve this last step.
So I ended up skipping the export and simply doing:
v.to.rast input=VectorGrid output=glwdFinalRast use=attr
Where VectorGrid = grid92 in your example.
As far as I can see, this actually works!
Thank you very much for your help and for staying with me to the bitter end!
