Ian Lance Taylor 27b68474ca cmd/cgo: run cgo pointer checks for pointer to union
If a C union type (or a C++ class type) can contain a pointer field,
then run the cgo checks on pointers to that type. This will test the
pointer as though it were an unsafe.Pointer, and will crash if it points
to Go memory that contains a pointer.

Fixes #15942.

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See https://golang.org/doc/install or doc/install.html for more details.
