Hi all, I can't seem to find this documented, and I'm me involved in some conversations about using plugins: What guarantees or limitations surround plugins? Can I compile a host program with go-1.8.0 and have a third-party plugin compiled with 1.8.1, and load it? Can I call methods on plugin-s

AFAIK, the only thing that can cause this in Go 1.8 is a non-preemptible loop. It's not related to the heap size at all. To test this theory, you can set GOEXPERIMENT=preemptibleloops and rebuild your Go tree (the compiler has to be built with this, so you can't just turn it on to build your proje
