Passing to C issue

[antono2]

Describe the bug

Here https://github.com/antono2/tmp/blob/603637399d22d4205af468cd6b634f2f64eefdb1/main.v#L118 I'd like to pass a pointer to C, but get

error: invalid initializer
 6334 |         main__Struct_array __tmp_arg_1 = param;

And using C.struct_array instead of alias

error: unknown type name ‘C__struct_array’; did you mean ‘struct_array’?
 6334 |         C__struct_array __tmp_arg_1 = param;

Reproduction Steps

git clone --depth=1 https://github.com/antono2/tmp && cd tmp && git checkout 603637399d22d4205af468cd6b634f2f64eefdb1 && v -show-c-output -cc gcc run .

Expected Behavior

Call set_struct_array in include/array.c

Current Behavior

/tmp/v_1000/tmp.01JPPP02KCQ7864DRP1NQT4M0Q.tmp.c: In function ‘main__set_struct_array’:
/tmp/v_1000/tmp.01JPPP02KCQ7864DRP1NQT4M0Q.tmp.c:6334:42: error: invalid initializer
