Description
Please answer these questions before submitting your issue. Thanks!
What version of Go are you using (go version)?
go version devel +c814ac4 Thu Jul 19 21:30:27 2018 +0000 linux/amd64
-> go1.11beta2
Does this issue reproduce with the latest release?
No, it wasn't the case in go1.11beta1
What operating system and processor architecture are you using (go env)?

What did you do?
I uses go tool cgo -godefs godefs.go with godefs.go :
package godefs
/*
typedef struct st_timespec {
int tv_sec;
int tv_nsec;
} st_timespec_t;
struct stat {
int var1;
st_timespec_t atim;
int var2;
};
*/
import "C"
type Stat_t C.struct_stat
type StTimespec_t C.st_timespec_t
What did you expect to see?
// Code generated by cmd/cgo -godefs; DO NOT EDIT.
// cgo -godefs godefs.go
package godefs
type Stat_t struct {
Var1 int32
Atim StTimespec_t
Var2 int32
}
type StTimespec_t struct {
Sec int32
Nsec int32
}
What did you see instead?
// Code generated by cmd/cgo -godefs; DO NOT EDIT.
// cgo -godefs godefs.go
package godefs
type Stat_t struct {
Var1 int32
Atim _Ctype_struct_st_timespec
Var2 int32
}
type StTimespec_t struct {
Sec int32
Nsec int32
}
If the new feature "recordTypedefs" is removed, everything is alright:
Commenting this line: https://github.com/golang/go/blob/master/src/cmd/cgo/gcc.go#L567, is enough to bypass this bug.
