Error when initializing unboxed types

[arthurpaulino]

Description

Initialization is not working for unboxed types like UInt64 and Bool on compiled code

Steps to Reproduce

Start a file like this:

initialize test : UInt64 ← pure 0

def main : IO Unit :=
  IO.println test

Then compile and run it.

Expected behavior:

It should output 0

Actual behavior:

It breaks with an error like this:

error: incompatible pointer to integer conversion assigning to 'uint64_t' (aka 'unsigned long') from 'b_lean_obj_res' (aka 'lean_object *') [-Wint-conversion]
l_test = lean_io_result_get_value(res);
       ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

Reproduces how often:

Everytime it's executed as compiled code. Although it works on the kernel.
