Description

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

Does this issue reproduce with the latest release?

Y

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

What did you do?

go build -buildmode=plugin -o ./handler.so ./main.go

Then when I tried to use it with another program:

2023/09/29 02:11:29 main.go:26: plugin error: plugin.Open("/plugin/handler"): plugin was built with a different version of package google.golang.org/protobuf/internal/pragma

What did you expect to see?

It should tell me what the different version is so I can match it.

What did you see instead?

Nothing other than a not very useful message telling me that I have the wrong version, but not what the correct version should be.

Research direction
Inspect the plugin package's Open function to identify where the version mismatch error is generated, then modify it to include both the expected and actual versions.
