Case in point: I just got this error on a v.in.ascii import of a ~200mb csv
file with points:
G_realloc: out of memory (I have 4gb RAM and plenty of swap space, and the
program never hit that limit anyway).
I'm pretty sure this binary is *not* compiled for 64-bit macs, so I may
recompile GRASS myself...
Sorry, I meant > 4gb (these files are probably going to be up to 8gb in
