non-incremental/QF_ABV/brummayerbiere/dubreva004ue.smt2 

We reverse an array of length 4 twice in memory at 4 positions.
We show via extensionality that memory has to be equal.

In one case swapping elements is done via XOR in the following way:
x ^= y;
y ^= x;
x ^= y;
In the other case the elements are just swapped.
