Sorry for the late answer.

Without looking at the specific code: You are most likely right. There are many memory leaks.

To simplify finding/verifying such issues, build it like this:

mkdir build-wakaama && cd build-wakaama
cmake ../ -DCMAKE_C_FLAGS="-fsanitize=leak" -DCMAKE_EXE_LINKER_FLAGS="-fsanitize=leak" -DCMAKE_BUILD_TYPE=Debug
make

When running any binary, it will show you found memory leaks when it exits.
