Looks like there is a memory leak using the new citrus/oficonv lib:

curl -O https://dclunie.com/images/charset/charsettests.20070405.tar.bz2
tar xf charsettests.20070405.tar.bz2
valgrind  --leak-check=full --show-leak-kinds=all dcm2json
charsettests/SCSARAB  output.json

I cannot reproduce the symptoms using default glibc/iconv (dcmtk 3.6.7-9).

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

   export ICONV_MAX_REUSE=0
   valgrind  --leak-check=full ...

Which gives now the reduced set of leaks:
