jpegls-hdf5-filter's Issues

Optimized build `-O2` causes memory leak in libhdf5-dev 1.10.0-patch1

Known bugs: On Ubuntu 18.04 hosting libhdf5-dev 1.10.0-patch1, compiling the library with -O2 optimization flag will cause memory leak in H5PL_load.

This problem does not exist on Ubuntu 20.04 hosting HDF5 >=1.10.3.

Steps to recreate the issue:

meson --buildtype=debugoptimized -Db_sanitize=address,undefined -Db_lundef=false build-debugoptimized/
cd build-debugoptimized
ninja test
cat meson-log/testlog.txt

Error log:

Software license

Hi @dswanepoel , thank you very much for hosting the software hdf5-jpegls-filter! I also enjoyed reading your publication at http://dx.doi.org/10.1080/17538947.2017.1301580

I would like to contribute to the project by modernizing the build steps, but first I would like to determine what software license you use. May I suggest the MIT license attributed to your name?

For your reference, here's draft of the license content: #2
