Comment:

 I imported the attached file into GRASS 70: v.in.ogr worked. Then I tried

 {{{
 v.out.ascii augstumpunkti1
 ...
 *** glibc detected *** v.out.ascii: realloc(): invalid next size:
 0x0000000001409a00 ***
 ...
 }}}

 It crashes in GRASS 7.svn r52794 in lib/vector/Vlib/ascii.c, line 529
 (G_rasprintf())

 Import with 6.4.svn still fails:
 {{{
