原因：
必须先 gdb program 然后source才可以，

问题：

(gdb) source /Users/sherlock/documents/go/src/runtime/runtime-gdb.py
Loading Go Runtime support.
Traceback (most recent call last):
File “/Users/sherlock/documents/go/src/runtime/runtime-gdb.py”, line 205, in
_rctp_type = gdb.lookup_type("struct runtime.rtype").pointer()
gdb.error: No struct type named runtime.rtype.

解决方案:

1. git clone https://github.com/golang/example.git

2.在stringutil目录下 go test -c ./

3.

gdb -q ./stringutil.test
Reading symbols from ./stringutil.test…done.

4.命令行

5.得出结论

6.修改runtime-gdb.py第205行rtype改成_type
注：我的平台是mac os x 10.10.3 ,go1.4.2

其他平台可能不是

struct []*runtime._type;
