#    void foo(int[] f, ...) {
#        foreach(int i, TypeInfo ti; _arguments) { }
#    }

#    void bar(out int[] f, ...) {
#        foreach(int i, TypeInfo ti; _arguments) { }
#    }

both functions compile just fine, however if you try to call 'bar' you will get Access Violation.

reason: pointer to typeinfo table is not being pushed, instead of pushing number of variadic arguments offset of this number is being pushed.
