 > Done in r71193 for v.net.iso (new flag -u). The newly created attribute
 table has the fields cat (category value), ocat (original category value),
 center (category value of nearest center), isonr (iso band number), isolbl
 (iso band label). A side effect is that a line is now correctly split if
 it is assigned to two different centers.

 Works great, thanks ! And the output is very useful, and probably more
 intuitive for many.

 This one segfaults for me when doing the following:


 {{{
 v.net streets_wake points=schools_wake op=connect out=network thresh=99999
 v.net.alloc -u network ccats=1-5 out=alloc
 }}}

 valgrind reports the issue to be on line 344 of main.c:


 {{{
 Invalid read of size 4
 ==3597==    at 0x10B588: main (main.c:344)
 ==3597==  Address 0x10 is not stack'd, malloc'd or (recently) free'd
 }}}
