Bug description:
  Dear package maintainers of dcmtk, libdcmtk14, libdcmtk-dev,

  Today, we have applied the latest update 3.6.4-2.1ubuntu0.1. See details https://ubuntu.pkgs.org/20.04/ubuntu-updates-universe-arm64/libdcmtk14_3.6.4-2.1ubuntu0.1_arm64.deb.html
  '
  When running the dcmtk tool storescu, sending data is performed correctly, but the tool crashes. The last 3 lines of the command line output are:
  I: Received Store Response (Success)
  I: Releasing Association
  Segmentation fault (core dumped)

  According to our analysis, the code crashes when function
  ASC_destroyAssociation(...) is called.

  If I downgrade to package version 3.6.4-2.1build2, everything works
  fine.

  Could you please investigate this issue?

  Bye,
  Andreas Zolnay
