nogo: unexpected container type in IndexExpr

[uhthomas]

What version of rules_go are you using?

0.32.0

What version of gazelle are you using?

0.25.0

What version of Bazel are you using?

5.1.2

Does this issue reproduce with the latest releases of all the above?

Yes.

What operating system and processor architecture are you using?

macos aarch64, also tested on Linux x86_64

Any other potentially useful information about your toolchain?

Seems related to https://github.com/golang/go/issues/52834, but using golang.org/x/tools v0.1.11-0.20220518213611-904e24e9fcf9 does not seem to make a difference.

What did you do?

nogo(
    name = "nogo",
    visibility = ["//visibility:public"],
    deps = ["@org_golang_x_tools//go/analysis/passes/buildssa"],
)

type A struct{}

func someFunc[T any]() {}

var _ = someFunc[A]

What did you expect to see?

A successful build.

What did you see instead?

We're seeing the same with rules_go 0.33.0
