Thanks for reporting this! Do you have a minimal reproducible example? Or do you have some code in general we can use to reproduce the issue?

Trying to get that now. The project triggering this on is closed source.

sixcolors · 2022-12-08T18:17:30Z

Okay, this one has the issue: https://github.com/sixcolors/fiber-boilerplate

sixcolors · 2022-12-08T18:37:51Z

Note: no panic when run with go version go1.19.4 darwin/amd64 or go version go1.19.4 linux/amd64 installed

zpavlinovic · 2022-12-08T18:46:51Z

Same here, I get no errors for the newer version, but do get it for, say, 1.19.1.

This is likely related to changes to the type checker, which ultimately affect call graph construction. Will investigate. Thanks for the info!

This did not happen like last week, nothing changed in this area of code.

zpavlinovic · 2022-12-12T19:32:32Z

That is a different issue. It is related to the ssa package. I will investigate and see if there is a simple fix. If not, I will open a separate issue. Can you tell me the Go version you are using?
