 v.net.salesman does something wrong during memory allocation. Normaly it
 results into assertion in malloc call.
 {{{
 v.net.salesman: malloc.c:4633: _int_malloc: Assertion
 `victim->fd_nextsize->bk_nextsize == victim' failed.
 }}}
 Valgrind reports invalid write (will attach full valgrind output as an
 attachment).
 {{{
 Number of cities: [6]
 ==6589== Invalid write of size 8
 ==6589==    at 0x401FAF: main (main.c:209)
 ==6589==  Address 0xd18cbc8 is 0 bytes after a block of size 40 alloc'd

 }}}

 GRASS 6.4 r41215 on ~AMD64 Gentoo.
 6.5 is also affected.

 I'm unable to reproduce with Spearfish. Will attach sample dataset.
