Please answer these questions before submitting your issue. Thanks!

What version of Go are you using (go version)?

go version go1.8.3 linux/arm64

Does this issue reproduce with the latest release?

Yes

What operating system and processor architecture are you using (go env)?

GOARCH="arm64"
GOBIN=""
GOEXE=""
GOHOSTARCH="arm64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/root/go"
GORACE=""
GOROOT="/usr/lib/golang"
GOTOOLDIR="/usr/lib/golang/pkg/tool/linux_arm64"
GCCGO="gccgo"

CGO_LDFLAGS="-g -O2"

What did you do?

If possible, provide a recipe for reproducing the error.
A complete runnable program is good.
A link on play.golang.org is best.

I use "go build -v -o demo.so -buildmode=plugin demo.go" to build go plugin demo.so.
Then I use "plugin.Open(/path/to/demo.so)" to open the plugin in the run-time.

What did you expect to see?

The plugin demo.so could successfully be loaded into process and run.

What did you see instead?

My process got panic. Please see the call stack as below:

There have been a number of plugin fixes in more recent releases. Can you let us know whether this still fails with the 1.10.1 release?

I did a test in "go version go1.10.1 linux/arm64", this still fails...

Since it has been fixed，which version I can use

[cherrymui]

It should work with Go 1.11 and newer.
