The Go builders (and standard development cycle) for programs on iOS require running the programs under lldb. Unfortunately lldb intercepts SIGSEGV and will not give it back. https://llvm.org/bugs/show_bug.cgi?id=22868 We get around this by never letting lldb see the SIGSEGV. On darwin, Unix signals are emulated on top of mach exceptions. The debugger registers a task-level mach exception handler. We register a thread-level exception handler which acts as a faux signal handler. The thread-level handler gets precedence over the task-level handler, so we can turn the exception EXC_BAD_ACCESS into a panic before lldb can see it.

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.
