Memory leaks in defaultConfig

[CarterLi]

Every config field ( including module arg ) should be freed / destroyed on program exit

They won't allocate memory by default. However if users set options ( eg. --lib-pci "/path/to/library.so" ) memory will be allocated for storing the option value and will never be freed.

There is no point in freeing blocks at the end of a program, because all of the program’s space is given back to the system when the process terminates.

Yeah. Technically we could never free memories since all modules are executed only once. However we still try hard to free them because that is a well coded program should do.

We could have chosen a memory-safe programming language ( even with GC ), but we chose C. It's our duty to do these dirty things.

and more important: asan complains about them
