I'm quite new to this initiative, but I work with a few other initiative in
other project. What is the process for relevant maintainer to gain access to the
reproducing code ? Specifically this issue has been looked at by Hans, but he
never figured out what the robot found and could reproduce.

With ZDI and other initiative, we have private back channel, and they provide C
code so we can go straight into fixing and validating.

cheers,
Nicolas
