What did you do?

pkg.go:

package pkg

func Test[T int](in int) {}

go.mod:

module mypkg

go 1.18

main.go:

package main

import (
	"mypkg/pkg"
)

func main() {
	pkg.Test[int](1)
}

What did you see instead?

# command-line-arguments
main.main: relocation target mypkg/pkg.Test[go.shape.int_0] not defined
