Fields missing from cgo structures when #pragma(pack) is used. #8110
Description
by fuzxxl:
The following code works under Go 1.2 but fails to compile with the most recent go tip
(4b3cdcb02f2d).
package cgotest
/*
#pragma pack(1)
struct foo {
char c;
int x;
};
*/
import "C"
import "unsafe"
func foo(f *C.struct_foo) int {
return int(f.x)
}
This is what the correspond _cgo_type.go looks like:
type _Ctype_char int8
type _Ctype_int int32
type _Ctype_struct_foo struct {
c _Ctype_char
_ [4]byte
}
In Go 1.2, the type definition used to have the x field instead of an underscore. This
looks like a regression to me.
