2.Compile the hdf5

$ cd hdf5
$ mkdir build && cd build
$ cmake ../ -DCMAKE_C_COMPILER=clang  -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_FLAGS="-fsanitize=address" -DCMAKE_CXX_FLAGS="-fsanitize=address"
$ make -j 32

3.run h5dump

$ cd bin
$ mkdir crashtest_dir
$ ./h5dump -r -d crashtest_dir/data poc

poc.zip
