[Debian-med-packaging] Bug#1056048: Acknowledgement (Memory leak in dcm2json)

[Mathieu Malaterre]

As pointed out by upstream, one must export the following:

<quote>
You should set the environment variable ICONV_MAX_REUSE to zero
before running such tests:

   export ICONV_MAX_REUSE=0
   valgrind  --leak-check=full ...
<quote>

Which gives now the reduced set of leaks:

% valgrind  --leak-check=full --show-leak-kinds=all dcm2json
charsettests/SCSARAB  output.json
