cannot find type `i32` in module `std::os::raw`

[ctaggart]

Input C/C++ Header

template <typename> class a {
  enum {};
};
template <typename> class b {};
namespace octave {
class c {
  b<a<char>> d;
};
}

Bindgen Invocation

~/rust-bindgen/target/debug/bindgen \
    --output __bindgen.rs \
    --enable-cxx-namespaces \
    --use-core \
    __bindgen.ii \
    -- -v -x c++ -std=c++11

Actual Results

How do I pretty print this on multiple lines like it used to?

/* automatically generated by rust-bindgen */

# [ allow ( non_snake_case , non_camel_case_types , non_upper_case_globals ) ] pub mod root { # [ allow ( unused_imports ) ] use self :: super :: root ; # [ repr ( C ) ] # [ derive ( Debug , Copy , Clone ) ] pub struct a { pub _address : u8 , } pub type a__bindgen_ty_1 = :: std :: os :: raw :: i32 ; # [ repr ( C ) ] # [ derive ( Debug , Copy , Clone ) ] pub struct b { pub _address : u8 , } pub mod octave { # [ allow ( unused_imports ) ] use self :: super :: super :: root ; # [ repr ( C ) ] # [ derive ( Debug , Copy ) ] pub struct c { pub d : root :: b , } # [ test ] fn bindgen_test_layout_c ( ) { assert_eq !

( :: core :: mem :: align_of :: < root :: b > ( ) , 1usize , concat ! ( "Alignment of template specialization: " , stringify ! ( root :: b ) ) ) ; } }

Expected Results

Instead of

pub type a__bindgen_ty_1 = :: std :: os :: raw :: i32 ;

It would be

pub type a__bindgen_ty_1 = i32 ;

or

pub type a__bindgen_ty_1 = :: std :: os :: raw :: c_int ;

This is a regression from 0df8441, astonishing that we hadn't found it before. Thanks a lot for the report!
