Hi John, I pulled the latest commit from 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 On Tue, May 31, 2016 at 11:37 AM John Detter <jdet...@wisc.edu> wrote: > Mohamed, > > Are you sure you are using the latest master?
