This fixes #16330
I introduced a bug when I ported PR #1976 to the current code base.
To get the
currietArgInfosI should have calledGetValReprTypeInFSharpForm, not GetTopTauTypeInFSharpForm.The bug is an effect of feeding the wrong
tauintoGetTopTauTypeInFSharpForm.It's wrong because I used
destTopForallTyonfty, which results in unequal lengths ofnArgInfosargTysinside ofGetTopTauTypeInFSharpFormBy using
GetValReprTypeInFSharpFormthe correct args are passed todestTopForallTyandnArgInfosandargTys.Lengthare of equal length.I also added two regression tests.
