If an XML tag doesn't contain anything inside, pText will be NULL. If that happens without being checked, then NULL will be passed to SDL_strcmp(). SDL_strcmp() will either call libc strcmp() or use its own implementation; both implementations will still dereference the NULL without checking it. This is undefined behavior, so I'm fixing it. The solution is to do what is done with all other XML parsing functions, and to make sure pText gets set to a safe empty string (which is just a pointer to a null terminator) if it happens to be NULL.
This is the source code to VVVVVV, version 2.0+. For more context about this release, see the announcement on Terry's blog!
