OK I modified it and will respin once v6.2 is released.

Also test_with_dies() should be split in 2 tests: valid/invalid;
then smp_parse_test() should split tests further regarding the
socket preference. But I'll let that to you, I wanted to 1/ fix
our Windows CI and 2/ show you how to structure the tests.
