--- Comment #9 from Ian Lance Taylor <ian at airs dot com> --- Thanks for the test case. I wrote a completely different test case that is more like the existing reflect tests: https://codereview.appspot.com/151280043/ . This test passes with gc but fails with gccgo at present on amd64: --- FAIL: TestVariadicMethodValue (0.00 seconds) panic: reflect: cannot use []reflect_test.Point as type reflect_test.Point in Call [recovered] panic: reflect: cannot use []reflect_test.Point as type reflect_test.Point in Call
