go version devel +2113c9a Tue Oct 25 07:51:17 2016 +0000 linux/amd64

I defined two plugin packages, local/foo and local/foo/foo, each defining
a global symbol X.

I opened both with plugin.Open. On the second open, I see this panic:

panic: runtime error: slice bounds out of range

goroutine 1 [running]:
panic(0x530460, 0x7ae830)
    /home/rog/go/src/runtime/panic.go:531 +0x1a0
plugin.lastmoduleinit(0x54e11f)
    /home/rog/go/src/runtime/plugin.go:39 +0x16a
plugin.open(0x54e142, 0x3, 0x0, 0x0, 0x0)
    /home/rog/go/src/plugin/plugin_dlopen.go:76 +0x2d2
