From the comment in SDL_filesystem.h:
Please call SDL_free() on the pointer when you are done with it

When building the project with MSVC, I ran into some debug heap asserts early into the program startup.
The culprit appears to be the code in m_config.c that does free(prefdir) as changing these to SDL_free(prefdir) resolved the issue.

I'm not sure what to do about `GetDefaultConfi

So, after running CMAKE and creating the VS 2017 projects, the solution isn't compiling. It gives a invalid numeric argument /Wextra for a lot of projects.
How to fix that?

I have used this library and its not capturing Swift run time exception or traces. This is only handling Objective C exception. If you could help me out for showing Swift run time exception with stack trace.
