This sounds like a general "C" programming issue and not relevant to
this list. However, since you're trying to use the expat interface,
here's some things to think about:
1. Did you allocate the C struct on the stack or on the heap? If on the
stack, it could be corrupted.
2. Did you call XML_SetUserData with the correct value in the second
argument?
3. How are you doing the cast? Any chance the address might change
during the cast? Which compiler is it? If you're using a modern compiler
or C++ you need to use reinterpret_cast<struct name*>(user_data).
