SWIG has always returned a typed interface value for a C++ class, so the interface value will never be nil even if the pointer itself is NULL. ptr == NULL in C/C++ should be ptr.Swigcptr() == 0 in Go. Fixes #9514. Change-Id: I3778b91acf54d2ff22d7427fbf2b6ec9b9ce3b43 Reviewed-on: https://go-review.googlesource.com/2440 Reviewed-by: Ian Lance Taylor <iant@golang.org>
