Cast warning while compiling src/task.c on 32-bit platform

[rickhg12hs]

I don't know if this is a problem or exactly how to test if it's a problem. Can this warning be ignored?

    CC src/task.o
task.c: In function ‘jl_lookup_code_address’:
task.c:661:66: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
         jl_tupleset(r, 4, jl_box_long((int64_t)ip));
                                                                  ^

Supposedly the result of this cast is undefined (iirc) and the pointer must be first cast to a intptr_t first. It would also silence the warning.
