If the area returned by sysReserve in mheap.sysAlloc is outside the usable arena, we sysFree it. We pass a fake stat pointer to sysFree because we haven't added the allocation to any stat at that point. However, we pass a 0 stat, so sysFree panics when it decrements the stat because the fake stat underflows. Fix this by setting the fake stat to the allocation size. Updates #13143 (this is a prerequisite to fixing that bug).

The Go Programming Language
Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.

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!

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.
