Bad Things(TM) seem to happen in Linux too when you do the same.

I'm seeing a consistent, reproducible crash in nmap running in Windows 2008
Server. It happens whenever you run nmap --interactive and perform two OS
scans in a row with "n -O -v <ipaddr>". Happens with both beta and stable,
both with precompiled binaries and running the source with Visual Studio. It
doesn't matter whether it's different addresses or not.

I see the first assert in PortList::initializePortMap() fails. I tried to
find where I should "clean" the ports object, but I'm having some
difficulty. Help?

------------------------------------------------------------
void PortList::initializePortMap(int protocol, u16 *ports, int portcount) {
 int i;
 int unused_zero;    // aren't we using 0 port?
 int ports_max = (protocol == IPPROTO_IP) ? 256 : 65536;
 int proto = INPROTO2PORTLISTPROTO(protocol);

 if(port_map[proto]!=NULL)
  fatal("%s: portmap for protocol %i already initialized", __func__,
protocol);

 assert(port_list_count[proto]==0);         // <===== THIS FAILS WHEN
RUNNING SECOND SCAN!
------------------------------------------------------------

Regards,
Juan
