Linearization of arrays & structs default initialization is done as if these objects would be an integer as large as the object. This integer is then simply zero-initialized. (This may be objectionable and will be done differently). However, sparse-llvm is not ready to handle this situation where a non-scalar is initialized with a scalar value. Workaround this by using LLVMConstNull() when possible.
