Valgrind errors during PDI_init and PC_parse_path

[AnidaKhizar]

Hello,

I noticed some valgrind errors when initializing PDI or when loading the conf tree with PC_parse_path. I used the following command on the small reproducer attached to the issue:

mpirun -np 1 valgrind --leak-check=full --show-leak-kinds=all --errors-for-leak-kinds=all --show-reachable=yes --num-callers=15 --track-origins=yes ./hello_world
