Did you also recompile the plugin with the new Go toolchain? It's a requirement of plugin support that the main program and all plugins be compiled with the same toolchain.
Yes, the loading program and the module were both compiled with the same toolchain. After the first occurence of the issue, I removed everything below $GOPATH and cleaned the cache, just to make sure everything got recompiled correctly - but the problem persists.
If loading and loaded module differ, I would expect a panic like "plugin was built with a different version" (I remember seeing that once) - but certainly not a panic in a regular expression parser.
