Crash when overloading * on a simple type

[dpsanders]

I did the overloading wrong, but this should give me a StackOverflow instead of crashing:

julia> struct MyType
       val
       end

julia> Base.:*(x::MyType, y) = MyType(x.val) * y

julia> x = MyType(3)
MyType(3)

julia> y = 4
4

julia> x * y
Bus error: 10

Stack overflows on linux so yes this is a dup.
