If a fault happens in malloc, inevitably the next thing that happens is a deadlock trying to allocate the panic value that says the fault happened. Stop doing that, two ways. First, reject panic in malloc just as we reject panic in garbage collection. Second, runtime.panicstring was using an error implementation backed by a Go string, so the interface held an allocated *string. Since the actual errors are C strings, define a new error implementation backed by a C char*, which needs no indirection and therefore no allocation. This second fix will avoid allocation for errors like nil panic derefs or division by zero, so it is worth doing even though the first fix should take care of faults during malloc.

README
This is the source code repository for the Go programming language.
For documentation about how to install and use Go,
visit http://golang.org/ or load doc/install.html in your web browser.
After installing Go, you can view a nicely formatted
doc/install.html by running godoc --http=:6060
and then visiting http://localhost:6060/doc/install.html.
Unless otherwise noted, the Go source files are distributed
under the BSD-style license found in the LICENSE file.

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.
