runtime: handle sysReserve failure in mHeap_SysAlloc sysReserve will return nil on failure - correctly handle this case and return nil to the caller. Currently, a failure will result in h.arena_end being set to psize, h.arena_used being set to zero and fun times ensue. On the openbsd/arm builder this has resulted in: runtime: address space conflict: map(0x0) = 0x40946000 fatal error: runtime: address space conflict When it should be reporting out of memory instead.

Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
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.
