Segmentation fault

[Behrang Gilanpour]

Hi!

the code below code segfaults... ive been staring at it for quite a bit
now, and i cant seem to see the problem. I would be really happy if you could
give me hints or atleast say whats wrong :)

Everything works fine with the first iterator... but when I try to do
_anything_ with the i2 it segfaults ...   even that cout << *i2
segfaults and i dont see why the first one works and not the second one :(
To me it seems like something goes very wrong in the
StringTokenizer::iterator  .. but i dunno... maybe my code is wrong some
how. Anyway, I would really appreciate some guidance...

Best regards,
  Behrang

(check below for gdb backtrace and my method's code)
(btw, you should change in your README file, it says address@hidden
 instead of address@hidden (bug-commonc++ is not deliverable))

this is from gdb:
