squid problems with "kill -HUP", was Re: ERR_FTP_DISABLED

Is anyone using the multiple-ports.patch successfully with 4 or more ports?

I'm not sure if this is related to the other core-dump problems that have
been reported here recently, but my squid cache is getting a SEGV
when accepting the first new connection after getting a sig-HUP.
I am using the multiple-ports.patch, and get core dumps
if I have 4 or more ports configured (no core dumps with 3 ports or less).
With some extra debugging turned on, I see the following:

[sent it a sighup, so it reconfigures]

[now I connect to the proxy, and get the following]

And the debugger reports:

I'm currently running squid-1.NOVM.16 under BSD/os 3.0, but I've seen the
same problem with squid-1.1.15 ... in both cases with multiple-ports.patch

Any idea what's going wrong?
