          Issue ID: 17128
           Summary: Wrong destructor call, if variables declared using
                    tuple of types.
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: critical
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: japplegame gmail.com

import std.stdio;
struct Foo {
    int val = 0;
        ~this() {
        writefln("destruct %s", val);
    }
}

void bar(ARGS...)() {
    ARGS args;
    args[0].val = 1;
    writefln("val = %s", args[0].val);
}

void main() {
    bar!Foo();
}

Excpected output:
val = 1
destruct 1

But got:
destruct 0
val = 1

It seems that the compiler destructs 'args' immediately after definition, not
at the end of the function.
