The `malloc()` function requires including the relevant header file ("stdlib.h" for C, "cstdlib.h" for C++). The pass would have to add to the module such an `emitc.include` op to the module or a forward declaration of `malloc()` using `emitc.declare_func` (in which case it can use `emitc.call` instead of `emitc.call_opaque`).
