For incomplete struct S, C.T and C.struct_S were interchangeable in Go 1.2 and earlier, because all incomplete types were interchangeable (even C.struct_S1 and C.struct_S2). CL 76450043, which fixed issue 7409, made different incomplete types different from Go's point of view, so that they were no longer completely interchangeable. However, imprecision about C.T and C.struct_S - really the same underlying C type - is the one behavior enabled by the bug that is most likely to be depended on by existing cgo code. Explicitly allow it, to keep that code working. Fixes #7786. LGTM=iant, r R=golang-codereviews, iant, r CC=golang-codereviews https://golang.org/cl/98580046 |
