[Simh] NetBSD 7.0+ halt on development version (and some earlier versions) simh - mac and linux

[Will Senn]

All,

  I am trying to run the latest netbsd in simh on the microvax 3900 sim 
according to the instructions found at 
https://www.netbsd.org/ports/vax/emulator-howto.html and I'm getting a 
halt. I tried it on the latest, but also on the 7.0 iso which apparently 
worked at some point. I also tried it on linux and it halted there as 
well. This issue has been raised previously, but I didn't see the 
resolution. Here is my mac run with simh and ini file:
