sizeof returns wrong value

[Bob Sidebotham]

In egcs-1.0 on both Linux and SunOS platforms, I get the following
inconsistency with sizeof. In two invocations of a constructor, passed
the identical array, the sizeof function returns two different values.
The only difference is that in the first instance, the constructor is
called during the creation of a temporary, and in the second instance
it is called to create a variable on the stack.

This is the smallest example I was able to come up with.

#include <iostream.h>

class choice {
public:
    template<class C> choice(const C& choices) {
	cout << sizeof(choices) << endl;
    }

    void noop() {};
};

main() {
    const char* list[] = { "foo", "bar", "baz" };
    choice(list).noop();
    choice foo(list);
}

On both platforms, the output is:

4
12

The correct output would be:

12
12
