  * Issue #167: G4 exceptions for certain run numbers

    can be closed now.
  * Issue #185: hits in both CALs from the same track

    interactions <https://github.com/JeffersonLab/HDGeant4/issues/187>.
    Richard will close this one after the meeting.
  * Issue #195: Crash adding daughters on RHEL/CentOS 8
    <https://github.com/JeffersonLab/HDGeant4/issues/195>. Hao Li first
    reported this crash in hdgeant4 last week . It comes during set-up
    of the geometry. Mark had this same crash hidden in his notes from
    back in March
    Mark suspects that this bug only shows up with GCC 8.4 and above.
    Richard remarked it could be a bug that was always there, but only
    gets exposed when the compiler version gets high enough.
  * Richard is putting together a CentOS 8 Docker container to have a
    look at Issue #195. We spent some time discussing issues around
    setting up CentOS to run the GlueX software stack. The "Powertools"
    repo is key.
