I am using Sage 10.0 on an M2 Silicon chip Macbook Air 13'.
 
Method of replicating bug: I accidentally used RSK on an element of SymmetricGroup(n) instead of an object of Permutation class. I don't think it's intended to work on the former, but this always kills the kernel for some reason. The entire notebook needs rerunning after that.

There is no rsk method on element of SymmetricGroup(n):
sage: s=SymmetricGroup(4).random_element()
sage: t=Permutations(4).random_element()
sage: t.robinson_schensted()
[[[1, 2], [3, 4]], [[1, 3], [2, 4]]]
sage: s.r[TAB]

@FrédéricC I remarked the same above. However, in this case, RSK should return a ValueError, and not kill the kernel instead. @Max Alekseyev thanks, I'll report my finding there.
