commit 6f48390ab209d16ee8f795f0a83677c8bd9ac69c Author: Father Chrysostomos Date: Wed Jan 4 23:28:54 2012 -0800 [perl #95548] Returned magical temps are not copied return and leavesub, for speed, were not copying temp variables with a refcount of 1, which is fine as long as the fact that it was not cop- ied is not observable. With magical variables, that *can* be observed, so we have to forego the optimisation and copy the variable if it’s magical. This obviously applies only to rvalue subs.
