 On Ubuntu 9.04, GRASS 6.4 (from deb packeage) and GRASS 6.5 (svn).

 When I run v.surf.rst with valid parameters program crash with this
 output:
 v.surf.rst tension=80.0 input=curvas elev=curvasMDT scolumn='cota'
 segmax=100 dmin=50

 *** glibc detected *** v.surf.rst: munmap_chunk(): invalid pointer:
 0xb7f85e60 ***

 Output (using valgrind):
 valgrind v.surf.rst tension=80.0 input=curvas elev=curvasMDT
 scolumn='cota' segmax=100 dmin=50
