Yes, it does persists.

Furthermore, changing lines 111-112 to
m3 = m2; m3 *= s1;
fixes the issue too.
Also, changing lines 370-371 in the main.cpp to
template<typename T, typename U>
bool test_is_equal(const T& actual, const U& expected)
solves the issue and I think that is the real fix. Passing aligned
types by value destroys the alignment.
