"WebBus errors occur when you're trying to access an address which doesn't exist. Check in your code you've assigned pointers correctly, especially uses of the * and & unaries, since * can dereference a pointer variable.

WebMay 13, 2011 · Violating Type Rules: It is undefined behavior to cast an int* to a float* and dereference it (accessing the "int" as if it were a "float"). C requires that these sorts of type conversions happen through memcpy: using pointer casts is not correct and undefined behavior results.
