When the prologue call to morestack was moved down to the bottom of the function, the pc/sp tables were not updated. If a traceback through a call to morestack is needed, it would get confused at and stop at morestack. Confirmed the fix by adding //go:systemstack (which calls morestackc, but same issue) where it did not belong and inspecting the crash.

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.
