What version of Go are you using (go version)?

go1.18.10 version
go version go1.18.10 darwin/arm64

Does this issue reproduce with the latest release?

Happens with 1.18 (I have tried with 1.18.9 and 1.18.10) but does not happen with 1.19 (tried with 1.19.3 and 1.19.5)

What operating system and processor architecture are you using (go env)?

What did you do?

Ran tests for https://github.com/stephenafamo/bob.

I have been able to provide a minimal example on the playground.

package main

func main() {
	_ = Table[*SelectQuery]{}
}

type SelectQuery struct{}

type Table[T any] struct{}

func (t *Table[T]) Query() *TableQuery[T] {
	return &TableQuery[T]{}
}

func (t *Table[T]) Insert() error {
	t.Query().Apply()
	return nil
}

type TableQuery[T any] struct {
	BaseQuery[*SelectQuery]
}

type BaseQuery[E any] struct {
	Expression E
}

func (b BaseQuery[E]) Apply(mods ...Mod[E]) {
	for _, mod := range mods {
		mod.Apply(b.Expression)
	}
}

type Mod[T any] interface {
	Apply(T)
}

What did you expect to see?

Compile and run the program successfully

What did you see instead?

./prog.go:16:17: internal compiler error: assertion failed

Please file a bug report including a short program that triggers the error.
