Maybe need t.IsPtrElem()?

Would you mind providing what repo causes this ICE? I tried git clone https://github.com/nzlov/dataloader.git then building successfully.

Sorry. Company project cannot be provided.

So to clarify, you get this error when importing github.com/nzlov /dataloader? Would you describe how did you use dataloader.{Loader,Config} in the package that import them?

@nzlov Thanks for the reproducible program. I was able to write a much smaller one, and have a fix in my local.

The problem was existed before 9ff91b9, and un-intentionally fixed in 4e565f7 (If you built the toolchain with commit 27a1454, you will see the same crash).
