Wrong layout

[e00E]

Input C/C++ Header

#pragma pack(push)
#pragma pack(1)
struct S5 {
   signed f0 : 11;
   unsigned f1 : 12;
   unsigned f2 : 23;
};
#pragma pack(pop)

Bindgen Invocation

$ bindgen failing.h -o failing.rs

Actual Results

While running bindgen we get:

ERROR:bindgen::codegen::struct_layout: Calculated wrong layout for S5, too more 2 bytes

but the output is created nonetheless:

[repr(C)]
#[derive(Debug, Copy)]
pub struct S5 {
    pub _bitfield_1: [u32; 2usize],
    pub __bindgen_align: [u8; 0usize],
}

Then when running the tests:

---- bindgen_test_layout_S5 stdout ----
        thread 'bindgen_test_layout_S5' panicked at 'assertion failed: `(left == right)`
  left: `8`,
 right: `6`: Size of: S5', failing.rs:11:4

Expected Results

Dupe of #537. Thanks for the report!
