Now this C++ struct inherits another one and the error is reported in C code expecting the base struct. If I only memset the base struct the error is still reported, which should be impossible. Code summary of the weirdness: struct ListDrawState : public DrawState { ... }; extern "C" void draw_func(DrawState*); ListDrawState ds; memset(&ds, 0, sizeof(DrawState)); // Error in draw_func()I don't think that this is legal C++. You can't assume that a C++ class object has the same kind of memory layout as a POD C struct.
That's not any part of the problem code though, so it's not really relevant to the original problem. There's no way we can comment on the original problem though because we can't actually see any of the code, only a few top level highlights which is nowhere near enough to tell us anything about what is happening.
