Hi Michael,
Based on other discussion which has already taken place about this,
I would appreciate it if you could create an issue at
https://github.com/simh/simh/issues
In your description please provide the above AND:
1) The contents configuration file you are running the simulator with
$ cat boot.ini
set cpu idle=32v
set rq0 ra81
att rq0 rq.dsk
set rq1 dis
set rq2 dis
set rq3 dis
set rp dis
set lpt dis
set rl dis
set tq dis
set tu dis
att ts 43.tap
set tti 7b
set tto 7b
load -o boot42 0
d r10 9
d r11 0
set dz lines=8
att dz 8888
set dz 7b
run 2
2) The output of:

3) Possibly a pointer to the disk image you're booting (compressed and visible
in a Google
Drive or other publically accessible file exchange environment (web site, Sky
Drive, DropBox, etc...).

4) As complete a description of your OSX system and compiler version as you
can easily put together.
It's a mid-2011 21.5 inch imac, 12 gigs of ram, i5 quadcore cpu running
at 2.4ghz, OSX 10.11.3, 2015 XCode (I'm not sure where the version info
for that is), gcc -v shows:
gcc -v
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.0.2 (clang-700.1.81)
Target: x86_64-apple-darwin15.3.0
Thread model: posix
I'm going to copy and paste your questions and my answers into a comment
on the github issue for reference.
If I can reproduce the problem it certainly can be fixed. Paul's observations
about
"does break strict-aliasing rules" might be relevant.
Thanks.
- Mark
