Hi Libjit developers,
I am Simone Campanoni (author of ILDJIT), I would like to report few
memory errors I had on Libjit used within ILDJIT.
I am using the last version of the official git repository.
Following you can find the output of the valgrind tool.
I hope you find this information useful.
Thanks
simone
