The layout code has to date insisted on stack frames that are 16-aligned including the saved LR, and it ensured this by growing the frame itself. This breaks code that refers to values near the top of the frame by positive offset from SP, and in general it's too magical: if you see TEXT xxx, $N, you expect that the frame size is actually N, not sometimes N and sometimes N+8. This led to a serious bug in the compiler where ambiguously live values were not being zeroed correctly, which in turn triggered an assertion in the GC about finding only valid pointers. The compiler has been fixed to always emit aligned frames, and the hand-written assembly has also been fixed. Now that everything is aligned, make unaligned an error instead of something to "fix" silently. For #9880.

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.
