#1006 swig tries to call private constructor

[Roblovski]

In this test case, SWIG will generate a setter for Three::m called _wrap_Three_m_set, which tries to call Two's copy constructor (which is private). If you change "Two m;" to "One m;" SWIG behaves correctly and doesn't generate the setter -- that extra level of inheritance seems to confuse it. Tested with SWIG 1.3.38 & Python.

%module test;

%inline {
struct nocopy
{
nocopy() {}

    private:
        nocopy\(const nocopy&\);
        nocopy& operator=\(const nocopy&\);
\};

struct One: public nocopy \{\};
struct Two: public One \{\};
struct Three \{ Two m; \};

}

Still reproducible with git master. Here's the testcase without the sourceforge escaping damage:

%module test;

%inline {
struct nocopy
{
nocopy() {}

    private:
        nocopy(const nocopy&);
        nocopy& operator=(const nocopy&);
};

struct One: public nocopy {};
struct Two: public One {};
struct Three { Two m; };

}
