c ++ operator[uint] msvc x86 构建失败，构建良好的 x64

Question

为什么 x64 没有歧义并且构建良好，而 x86 失败？在编译器资源管理器中，任何相同的 32/64 编译器都会给出类似的结果：

<source>(24): error C2666: 'arrs<int,5>::operator []': 2 overloads have similar conversions
<source>(6): note: could be 'T &arrs<T,5>::operator [](uint32_t)'
        with
        [
            T=int
        ]
<source>(24): note: or       'built-in C++ operator[(T, int)'
        with
        [
            T=int
        ]
<source>(24): note: while trying to match the argument list '(arrs<int,5>, int)'

#include <cstdint>

template<class T, uint32_t N>
struct arrs
{
    T& operator[](uint32_t i)
    {
        return v[i];
    }

    operator T* ()
    {
        return v;
    }

    T v[N];

};


int main()
{
    arrs<int, 5> a;
    a[0] = 0;

    char x = 0;
}
