Yes:
http://grasswiki.osgeo.org/wiki/GRASS_GIS_Performance#Vector_geometry

"In all GRASS GIS versions,
 * with topology the feature limit is at time 2^31 - 1 (about 2
billion) features per vector map.
"

But you can disable topology to be build when importing:
v.in.ascii -b
 Do not build topology in points mode

See for more details: http://grass.osgeo.org/grass70/manuals/v.in.ascii.html

TODO: understand the limit when using the -b flag.
