[visit-developers] Crash on Mac ... hoping for pity from a network expert

I am running VisIt on my Mac on a wireless connection at NCSA. My hostname now shows up as "captive-wireless-250-136.ncsa.uiuc.edu". I can access the web and can log into remote machines. When I try to ssh to $(hostname), it gives me a prompt, but does not like my password. I suspect that means that it recognizes itself, but ssh'ing from external hosts is disabled somehow.
When I start up VisIt, it crashes. This is true for VisIt compiled against the trunk and for VisIt with -noloopback. HOWEVER: if I run visit V1.9.1, which is installed on my machine, it does not crash. I don't have V1.10 installed, so I can't get further info on what that version does.
The crash has been a bit tricky to narrow down (the segfault follows a bad page, so the stacktrace has no meaningful info).
It appears to be in "RemoteProcess::SingleThreadedAcceptSocket()". Specifically, it crashes in the accept call:
desc = accept(listenSocketNum, (struct sockaddr *)&sin, &len);
The listenSocketNum is set to 14, so it appears to be initialized somehow.
Any ideas out there?
