Hi, Mark,
I just opened an issue (https://github.com/simh/simh/issues/277) and
I'll post a comment to it with the information you requested.
I made this VM following a tutorial on gunkies, but the folder has a lot
of junk, so while I wait for gcc to compile I'll make, test and then
upload a pristine copy of the VM somewhere, and post that as a comment
to the issue I opened.

Hi Michael,

I grabbed simh_master.zip from github yesterday and compiled it on OSX and
in a virtualbox instance of Linux Mint 17. OSX is the native OS, Linux is in a
VM.
I have a 43BSD machine accessible to both on a shared drive. It will boot
normally when I run vax780 inside of the Linux VM, but when I run the
vax780 binary I compiled in OSX it crashes.
I'm assuming I should file a bug report on the OSX build? Should I post that
over at github and what do I need to include in the report?
I realize this is a very noob-ish mail, but I don't want to submit something
long and involved and find it's entirely irrelevant, so I'm asking here first.
if it helps, this is what the crash looks like:

When I run that under my linux VM, I get:

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
2) The output of:
sim> SHOW VERSION
on both your failing OSX environment AND the succeeding Linux Mint
environment
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.
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
