When we copy the stack, we need to adjust all BPs. We correctly adjust the ones on the stack, but we also need to adjust the one that is in g.sched.bp. Like CL 33754, no test as only kernel-gathered profiles will notice. Tests will come (in 1.9) with the implementation of #16638. The invariant should hold that every frame pointer points to somewhere within its stack. After this CL, it is mostly true, but something about cgo breaks it. The runtime checks are disabled until I figure that out. Update #16638 Fixes #18174 Change-Id: I6023ee64adc80574ee3e76491d4f0fa5ede3dbdb Reviewed-on: https://go-review.googlesource.com/33895 Reviewed-by: Austin Clements <austin@google.com> |

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.
Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
Go is the work of hundreds of contributors. We appreciate your help!
To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html
Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

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.
