This is true. I am also puzzled why I am unable to reproduce the issue
with GCC -- it is not even possible after switching to debug. I did
not look up what kind of expression s1*m1 returns but I am wondering
why it is causing trouble in this case since as you said, we are just
passing an expression. Maybe the expression is holding a fixed size
member? Like the matrix-matrix products.
