在Go（go1.2.1 linux / amd64）中运行http服务器时，我收到一个罕见的错误。
unexpected fault address 0xb84004
fatal error: fault
[signal 0x7 code=0x2 addr=0xb84004 pc=0x421d62]
goroutine 1 [running]:
unexpected fault address 0xacb59c
panic during panic
这只发生过一次，到目前为止，经过近一周的运行并且无法再现。但是，我仍然想知道这意味着什么以及如何发生这种情况。遗憾的是，我无法提供任何代码示例，因为我不知道它可能发生在哪里并且代码不是开源的（还），所以我正在寻找更一般的答案。任何人吗？
