Thanks for the report.  Linux vsnprintf returns the amount of space
needed when the buffer passed in is too short.  Nmap already has code
to lengthen the buffer in that case.  But Windows apparently just
returns -1.  I have just checked in a change to
nmap-exp/soc07/nmap/output.cc which grows the buffer in that case.
This should resolve it.  But if you still see the problem in the
latest SVN version or after the next release, please let us know.

Cheers,
