git.dyninst.org is now just a mirror and unfortunately it looks like it
isn't quite up to date. http://github.com/dyninst/dyninst will get you
the latest commits.
If you want to update your origin:
git remote remove origin
git remote add origin http://github.com/dyninst/dyninst
git pull origin master

Hi John,
I pulled the latest commit from git.dyninst.org
<http://git.dyninst.org>, which resulted in the error in my previous
email.
Now using a clone from the github path your provided, I am getting the
following message on stderr:
decodeOneOperand() called with unknown addressing method 18
And even though the output binary is created, it does not execute
(exec format error).
Again, I am testing with /usr/bin/ssh on Ubuntu 16.04, without any
instrumentation (open, get default module, get procedures, save).
Thanks,
Mohamed

Mohamed,
Are you sure you are using the latest master? In my version of
arch-x86.C line 7993 isn't inside the ia32_decode function. Could you
try pulling from master and rebuilding/rerunning? If you could provide
another stack trace that would be really helpful.
