The Go programming language

The 'continuation pc' is where the frame will continue execution, if anywhere. For a frame that stopped execution due to a CALL instruction, the continuation pc is immediately after the CALL. But for a frame that stopped execution due to a fault, the continuation pc is the pc after the most recent CALL to deferproc in that frame, or else 0. That is where execution will continue, if anywhere. The liveness information is only recorded for CALL instructions. This change makes sure that we never look for liveness information except for CALL instructions. Using a valid PC fixes crashes when a garbage collection or stack copying tries to process a stack frame that has faulted. Record continuation pc in heapdump (format change). Fixes #8048.

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 README). 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.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 doc/install.html for more details.
