The alloca allocation might interfere with pushing parameters on the stack for function calls. This was at least true for older compilers but I think it's still a valid concern.
Ah, I hadn't thought of that.Anyway, people on std-proposals have brought up issues with copy elision that seem hard to handle without compiler magic.
