Thanks for the report. @twocs Transferring to gopls issue tracker for triaging.

This panic is mysterious to me. Some kind of memory corruption?

@twocs which version of Go are you using?

internal/lsp: fix nil pointer in hover when (types.Object).Pkg() is nil
We haven't been able to reproduce this scenario, but it may be possible
when the user is in a broken state. Avoid panicking by gating every
use of obj.Pkg() with nil checks.

Not really sure what happened. I was moving my mouse to hover over a series of different lines when the panic occurred.

Thanks for investigating. That CL fixed a NPE in our code, but the panic above ("unexpected fault address 0xffffffffffffffff") points to some kind of runtime corruption. I don't think anything particularly implicates gopls or go/types, though I suppose perhaps this could be the result of some race that has gone undetected.

Given that this is the first report of its kind that we've received, unless it is reproducible I'm inclined to think it might be a problem with your computer. However, my runtime knowledge is limited.

It seems this is loading itab._type. It is quite weird that this field is bad. Is there anyway that I can reproduce this? Thanks.
