Infinite loop when calling `assert.NotZero` on a protoc-gen-go generated struct

[jvmakine]

This only happens if msg.String() has been called on the generated message

Using "github.com/alecthomas/assert/v2"

If proto.Resource is a struct generated from a proto file with protoc-gen-go

This never finishes

t.Run("protoc message is not zero", func(t *testing.T) {
    res := &proto.Resource{}
    _ = res.String()
    assert.NotZero(t, res)
})

While this works correctly

t.Run("protoc message is not zero", func(t *testing.T) {
    res := &proto.Resource{}
    assert.NotZero(t, res)
})
